Future Capability of the Armed Forces

Lord Bishop of Southwark Excerpts

Thursday 16th July 2026 Lords Chamber

[The Lord Bishop of Southwark (Valedictory Speech)]

My Lords, I am grateful to the noble Lord, Lord Harlech, for bringing this debate. Let me begin my valedictory address by making it clear that it is not my intention to advise His Majesty’s Government on the number of dreadnought battleships they should be laying down or what the future of the Blue Streak missile programme should be. I wish to address some wider issues that I believe are directly relevant to our future capability and which arise out of our current situation.

Quoting from the Global Peace Index 2026, the right reverend Prelate the Bishop of Norwich reminded the House during a debate on the Armed Forces Bill on 6 July that

“the world has continued its longstanding trajectory of deteriorating peacefulness”.

It has always been my contention that, since the UK left the European Union, the costs of our security, diplomatic efforts and cultural reach will need to rise, since we no longer benefit from the partnership and pooled resources that the union provides. Instead, our defence spending has stagnated and NATO is in difficulty, with the United States now in unpredictable mode. We are planning to reduce the Diplomatic Service, and the BBC and other major cultural players continue to make cuts.

I appreciate that, as we shall hear, a different trajectory is planned for UK defence. A good deal will be said about the changing nature of warfare in the light of the appalling assault on the territorial integrity of Ukraine by President Putin. However, the continued reduction in what we used to call manpower across all three services is worrying because, at the end of the day, fearful decisions need to be taken by human beings, and some situations should be addressed only by a human presence, not an AI-driven remote response. AI and drones are no substitute for physicality, presence and engagement.

It may seem strange to hint at a moral dimension in a business which is never decorous or happy, but the basis of international humanitarian law in conduct of war finds its origin in the Christian doctrine of a just war with its tests of necessity, proportionality and restraint. The Geneva conventions, our more elaborate and contemporary responses, were themselves born of fearful conflict and barbarity, not wishful thinking. Yet increasingly, in conflicts such as in Sudan, in the Russian invasion of Ukraine, and, I so regret to say it, in the manner in which Israel has responded to the Hamas atrocities of 7 October 2023, international law is set aside for reasons of expediency, and with appalling results and much innocent suffering, not least in Gaza. That is why the other issues I alluded to, such as the size and effectiveness of our diplomatic service, matter, and why good quality journalism matters, including British journalism and British values in the form of the BBC, to help uphold international rules, because when these become degraded, people suffer, and we all become less safe.

Finally, I wish to thank the House for the consideration given to the Lords spiritual and to me, for the great privilege of serving here, for the high calling of your Lordships and for the dedication of our staff, not least the doorkeepers, many of whom served in our Armed Forces. As someone who has led your Lordships in prayer at the beginning of business, I am reminded of the words of the noble and right reverend Lord, Lord Chartres, that “the largest party in this House is the praying party”. I give thanks for that and assure all your Lordships of my continued prayers.
