Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 1 April 2025 to Question 42031 on Ukraine: Peacekeeping Operations, what definition his Department uses of a just and lasting peace in Ukraine.

A just and lasting peace in Ukraine should be in accordance with the UN Charter. This must uphold Ukraine’s sovereignty and security, including by preventing renewed Russian aggression.

As the Prime Minister said in Paris on 27 March 2025, “robust and credible security arrangements are the best way to ensure that any deal ends in a lasting peace", and "Ukraine must be able to defend itself and deter future Russian aggression".

The UK is taking a leading role in supporting efforts to achieve such a peace and to build a coalition of the willing to support Ukraine’s future security.
