Iran

James MacCleary Excerpts

Wednesday 15th July 2026 Commons Chamber

[James MacCleary (Lewes) (LD)]

The picture in Iran remains volatile. We have seen renewed military strikes, threats against ships in international waters and rhetoric that keeps ratcheting upwards. Put together, that is the kind of mix that tips into a spiral that nobody in this House wants. The Liberal Democrat position has not shifted on this issue, and our leader has been consistent in this House. We opposed escalating the situation militarily from the start, because it contravenes international law and because middle eastern conflicts have a track record of running on long after the promises made at the outset, and of leaving the region worse off than it was before.

What is needed now is diplomacy and restraint, backed by a real commitment to keep the situation from tipping back into something far worse. The UK Government should be working every diplomatic channel they have to get Washington and Tehran back to the negotiating table as soon as possible. Let me be clear: this was an illegal war started by a reckless and irresponsible President. Trump, together with Benjamin Netanyahu, led the US and Israel into this war without a plan. As a result, NATO is less secure and Trump has been humiliated by his arrogance. None of this excuses Tehran, however. The regime bears real responsibility for the instability we are seeing. It is funding terror groups such as Hamas, Hezbollah and the Houthis, targeting shipping lanes, holding foreign nationals without cause and crushing dissent at home. Iran can also never be allowed to develop nuclear weapons, but that goal must be achieved through diplomacy not through force of arms.

Roughly a fifth of the world’s traded oil moves through the strait of Hormuz, so anything that threatens shipping there shows up quickly in household budgets here in Britain, not just in the Gulf. Iran’s attacks on commercial vessels, on top of President Trump’s now aborted proposal to start charging for passage through the strait, have made already jittery markets more nervous still. Freedom of navigation is foundational to how trade works around the world. Shipping lanes should not be turned into leverage. The strait needs to stay open, secure and governed by international law, full stop.

This Government should be co-ordinating with allies to steady the situation, keep commercial shipping protected and bring down the odds of things escalating further at sea. The fallout does not stay offshore.

[Sir Alec Shelbrooke]

The hon. Gentleman said that we should be keeping shipping protected. How does he see that happening? What does he think needs to be protected, and from what area?

[James MacCleary]

Primarily, shipping needs to be protected from attacks in the strait of Hormuz. The first way to do that is to reach a settlement that keeps shipping safe in the strait of Hormuz and, as I said in my previous point, that is why we need to reach a diplomatic solution. A military solution is not going to keep shipping safe, because ultimately, shipping companies assess things by risk and as long as shipping is held to be at any risk in the strait of Hormuz, we will not see a resumption of previous trade levels.

The fallout does not stay offshore. When oil prices climb, it is British households—our constituents—who feel it in transport costs, in the weekly shop and in energy bills. I hear daily from constituents who are feeling the financial pressure. Families who are already stretched thin do not need another external shock landing on top. The Government should not just be waiting for markets to calm down on their own. There are concrete steps available, including cutting fuel duty, bringing rail fares down, keeping on pushing bus fares lower and scrapping VAT on electric vehicle charging. All of that would ease the everyday cost of getting around. This moment should also sharpen the case for building real energy resilience at home.

[Dr Evans]

Does the hon. Gentleman have an estimate of how much those policies would cost?

[James MacCleary]

Yes, of course. All our proposals are fully costed, and if the hon. Gentleman would like me to do so, I can send him more information on how we would pay for them. Every time that instability somewhere else sends a shockwave through our economy, it is a reminder of why weaning ourselves off volatile fossil fuel markets is squarely in Britain’s interests.

I would also like to raise the situation facing British citizens held in Iran. Lindsay and Craig Foreman have now been in Evin prison for over a year, and today there are reports that Craig’s sentence has been extended by a further two years. There are reports of hunger strikes and conditions that remain harrowing. No British national should be used as a bargaining chip in a geopolitical stand-off. Their continued detention is not acceptable, and the Government need to treat their release as an urgent diplomatic priority, working with international partners to get them home.

[Gregory Stafford]

The hon. Gentleman has just outlined a number of ways that Tehran does not respect international law and uses human capital as a bargaining chip, but in the same breath, he mentions that he does not see that there needs to be a military solution and that he believes that somehow Iran can be brought to the table to get a diplomatic solution. How can those two things be compatible?

[James MacCleary]

It is a good challenge. Obviously, what I am talking about is a long-term solution. The military option has been tried. The United States, the pre-eminent military power on Earth, has expended a huge number of missiles and other military assets to try to bring Iran to a position that it wants it to be in. This has clearly not worked: Iran is still attacking shipping in the strait, and we are still seeing instability in the area. It is clear that the military option has not succeeded, and if the Americans cannot do it, frankly probably nobody can. We need to go back to the negotiating table to try to find a diplomatic solution, which I accept has so far been out of reach, but if we want a stable solution in the long term, it will come through diplomacy, not military means.

I welcome the recent decision by the Government to designate the Islamic Revolutionary Guard Corps under the National Security Act 2023, but a designation on paper matters only if it is backed by enforcement. This House will expect the Government to act firmly against anyone on UK soil intimidating dissidents, running cyber-attacks on British institutions or acting at the bidding of a hostile state.

Finally, a word on Britain’s role: the Government have said that UK bases have been used by the US only for narrowly defined defensive purposes. That distinction is worth holding on to, and this House deserves ongoing clarity about exactly when and how British territory might be used if things escalate further. Our alliances matter, but they do not relieve the Government of a duty to make their own judgment calls on how sovereign UK territory is used.

The priority now has to be stopping any slide into a wider war in the region, starting with the rebuilding of diplomatic channels, keeping shipping lanes protected and holding the line on international law, while backing our allies without handing over our own judgment calls. Above all, it means remembering that every step further into escalation has real costs for civilians in the middle east and families here at home. It is a reminder of the limits of armed force and of the fact that one of this country’s greatest strengths is our soft power—diplomatic, financial, cultural. Britain has influence that it can use to cool this situation down, rebuild some diplomatic momentum and help get the region and the wider world to the stability that everyone so desperately needs.
