Arctic and High North

Al Carns Excerpts

Tuesday 13th January 2026 Westminster Hall

[The Minister for the Armed Forces (Al Carns)]

It is a delight to speak under your chairmanship, Ms Vaz. I thank my hon. Friend the Member for Dunfermline and Dollar (Graeme Downie) for securing this debate and for all his work as chair of the Labour back-bench defence committee. In an article published last week, he stressed the critical importance, in these volatile times, of strengthening the UK’s armed forces, preparing for the possibility of war and showing that although we do not want conflict, we are ready to fight to defend our freedoms and indeed our prosperity. He is absolutely correct and is speaking about an area with which he is all too familiar.

Geography really matters. Some members of the SNP may not be interested in defence, but, given Scotland’s geographical position, our adversaries are interested in Scotland because of what it offers to the UK, Europe and NATO defence.

[Mr Angus MacDonald]

Given that one of the UK’s core NATO responsibilities is securing freedom of operation in the GIUK gap, can the Minister reflect on what an SNP-led independent Scotland would mean for that task? At a time when hostile states exploit political fragmentation, does he agree that a party that opposes the nuclear deterrent, has turned away defence-related industrial investment in the Clyde and has even restricted medical aid to Ukrainian soldiers by classifying it as military support would weaken rather than strengthen our collective resilience in the High North?

[Al Carns]

The reality is that this is not about politics. This is about sincerity around our national security decisions. An independent Scotland would weaken not just the security of the UK—of Scotland, England, Wales and Northern Ireland—but the whole European security architecture and NATO as a whole. At this point in time, a worse decision could not possibly even be fathomed.

Some comments were made earlier about whether we have a frontline with Russia. The reality is that we do. As my hon. Friend the Member for Dunfermline and Dollar mentioned, it sits in the north Atlantic. When it comes to being scared of Russia, last time I checked the military dictionary, that word definitely did not exist. If someone from industry sees a Russian frigate or submarine near the CNI, I can guarantee that there will be a Royal Navy, NATO or European submarine or frigate very close by.

Although much of the current attention is focused on Ukraine, being ready to fight means being alert to every danger. We must continue working ever more closely with our allies to address emerging threats wherever they may arise. Today’s debate is a welcome opportunity to discuss a part of the world that is becoming increasingly contested by the major powers.

Having been largely inaccessible to navies in the past, the High North and Arctic are changing at an unprecedented and accelerating rate. Global warming is transforming the Arctic from frozen expanses to a 21st-century geopolitical hotspot. As melting ice opens up new sea routes, the established security balance across the top of the world will be fundamentally reshaped forever. Routes between the Atlantic and Pacific will become increasingly navigable for more of the year, bringing the continents of Asia, Europe and North America closer than ever before.

Competition to exploit the region’s valuable natural resources is growing, too. China is extending its activity in the Arctic, having recently sent more icebreakers and research vessels to probe its expanses and declaring itself a near-Arctic state. We are under no illusion about how the changing Arctic environment poses new challenges, both commercially and militarily.

Russia remains the most acute danger to the security of the northern near Atlantic, and its operations within a more navigable Arctic are an increasing part of that threat. It is sobering to realise that Vladimir Putin controls more than half of the entire Arctic’s coastline. The increased militarisation of Russia’s Arctic territory, including investment in bases and air and coastal defence capabilities, is of increasing concern. For example, Russia has established a new northern joint strategic command, reopening cold war-era bases above the Arctic circle, including a fully operational base on Franz Josef island and another on Kotelny island.

In the north Atlantic, Russian submarine activity is nearing the highest levels since the cold war. Changes in the region directly impact us and our security here in the UK, as one of the Arctic’s nearest neighbours—whether it is from increasing threats or damage to subsea electricity or telecommunication cables in the Baltic sea or from the increase in Russian activity in the key Greenland-Iceland-UK gap involving surface and sub-surface vessels and aircraft.

As climate change opens new routes and access to resources, and as we are one of the Arctic’s closest neighbours, how are the Government working with allies to strengthen our collective security in the region in the face of climate change to ensure that the UK is able to protect our long-term interests alongside other partners from non-Arctic states?

[Al Carns]

As my hon. Friend will know, we have various multilateral treaties, including working with the JEF and NATO to ensure that any implications from global warming are carefully considered and that security recommendations are put in place to deal with them should they arise.

NATO has made it clear that defence of the High North is a key strategic imperative. The addition of Sweden and Finland to the alliance has significantly strengthened NATO’s hand in the region. Indeed, Nordic countries have spent decades managing Moscow’s interests in the High North, and they bring valuable experience to help counter the threat that Putin’s forces present today. As part of the UK-led joint expeditionary force, we are working alongside them to enhance collective security across Northern Europe.

We have assets across all three main services and interoperability with our allies that can project force deep into the High North. For example, a recent agreement between Britain and Norway will see our commando forces, led by the Royal Marines, operating in Norway all year round to defend NATO’s northern flank. They will take part in Exercise Cold Response, the largest military exercise in Norway this year, with a 40% increase in Royal Marine activity. I know the exercise well: in 2022, I took part in it as the chief of staff of the UK strike force, operating a multinational fleet, dozens of ships, aircraft and thousands of forces across the Arctic. I spent time during my 24 years—many of it unhappy, in a snowhole—in the Arctic as part of the Royal Marines, as a mountain leader.

We train hard for those operations in the Arctic. We have some of the best troops in the world, and we work exceptionally hard with Norway and Sweden and with Finnish forces. What is more, we have established the littoral maritime response force, with dedicated personnel, ships and helicopters operating in the High North. We have bought new generation anti-submarine frigates, have just completed a huge deal with the Norwegians to ensure interoperability across the Type 26 fleet, and have launched the groundbreaking Atlantic Bastion programme to protect the UK from Russian undersea threats. It is all part of widespread and regular operations involving our armed forces to maintain operational readiness across northern Europe.

The MOD keeps Russia’s military posture in the region under continuous review and conducts wider strategic monitoring with our allies. Of course, we recognise that Russia is an Arctic state with a legitimate presence, but we have to be clear that we will protect, and if necessary assert, our rights to safeguard security and international law. That includes honouring the integrity—

I too was at the meeting of the APPG for Greenland, in a room nearby where we heard from Greenland’s Minister for business, mineral resources, energy, justice and gender equality. In addition to my hon. Friend’s important points about the military strength and prowess of this country and others, and about our alliances, does he agree that we need to send a very strong message about international law and the international rules-based system? That would give reassurance to the High North and Arctic countries, particularly Greenland, at this moment.

[Al Carns]

I completely agree. I think our Prime Minister has done exactly that, but the only people to decide the future of Greenland are those in Greenland, and NATO as a whole provides a collective security agreement for Greenland and other countries in the High North.

We cannot be naive about the challenges that we face. For example, the threat of damage to subsea electricity and telecommunications cables is an ongoing concern and underlines the importance of really close collaboration and interoperability with our European partners. Very simply, there can be no global security without security across the Arctic and northern Europe.

Let me move on to the points about Greenland. The past few weeks have seen an increasing focus on Greenland in the context of Arctic security, but the UK has been absolutely and utterly clear: the future of Greenland is a matter for the Greenlanders and the Danes, and no one else. Greenland, Denmark and the United States have worked closely since the second world war to ensure that this key territory is protected from various aggressors. That will always continue. Security in the Arctic must therefore be achieved collectively with NATO allies, including the United States, by upholding the principles of the UN charter—

[Valerie Vaz (in the Chair)]

Order.

On resuming—

[Al Carns]

Security in the Arctic must be achieved collectively, with NATO allies including the United States, by upholding the principles of the UN charter on sovereignty, territorial integrity and the inviolability of borders. These are universal principles and we will always defend them.

It is worth noting that we completed Exercise Tarassis, one of the biggest exercises in the High North, late last year. The next set of exercises in the High North is known as Lion Protector. We have a JEF chiefs of defence meeting coming up at the end of this week. Cold Response will take place, and is already under way, with a 40% increase in the Royal Marines deployed in the High North. They will be there all year round.

The RAF continues to patrol in the High North with various types of aircraft. Some bilateral outstanding agreements, such as the Lunna House agreement, have established interoperability like never before across our naval forces, particularly with Norway.

[Dr Al Pinkerton (Surrey Heath) (LD)]

Prior to our brief interruption, the Minister described a part of the world that is undergoing considerable change and turbulence, not least from climate change. Will he reflect on how UK procurement and military doctrine might have to go to a similar scale and rapidity of change in order to respond to, and reflect, the challenges of an increasingly liquified Arctic that is no longer in a frozen state?

[Al Carns]

For a long time during the cold war, a large proportion of our time was predisposed to looking to the high north-east and north-west in the Atlantic and the High North. It is a case of relearning some of our old lessons, and ensuring that our capability and technological mix is adapted into our doctrine, training tactics and procedures. For example, some of the work now going on in Exercise Cold Response is not necessarily about training; it is about actual mission set planning to prepare for the worst-case scenario, and that is how we are seeing it evolve through time. That will continue through the Lunna House agreement and various agreements we have with Sweden and Finland as part of the NATO alliance, so it will continue to get stronger. Importantly, we will never forget the JEF either, which is a super-important geopolitical alliance.

Politically and environmentally, the Arctic is in absolute flux. Rising temperatures are remoulding landscapes and turning centuries of certainty on their head. As the region grows increasingly contested, it is more important than ever for Britain to collaborate with like-minded states to uphold international law and strengthen our collective security. That is precisely what we are doing. We are working intensely with our partners to monitor threats, bolster our forces and stand up for our interests. As we boost defence spending to 5% of GDP over the next decade, protecting the stability and security of the High North and Arctic will be integral to our plans. That is how we will keep Britain secure at home and strong abroad.

Question put and agreed to.
