Dr Julian Lewis: On the question of the recommendations made by the ISC, may I welcome the steps taken by the House of Lords to clean up its act in relation to the registration of work undertaken for foreign Governments? On the NATO guarantee, does the Foreign Secretary agree that it is a solemn commitment by each member of NATO to, if necessary, go to war if any other member of NATO is attacked? Ukraine is not a member of NATO. Does she agree that it is important that we do not elide from the situation in Ukraine to the next step, which will be the Baltic states that are members of NATO. We have to be very clear about what our commitments really are.

[The Secretary of State for Foreign, Commonwealth and Development Affairs (Elizabeth Truss): My right hon. Friend is absolutely right about the NATO guarantee and its importance for NATO members, including the Baltic states. In December, I visited British troops forming part of NATO’s enhanced forward presence at Tapa in Estonia, where allies are helping to protect the border with Russia. We are working with our NATO partners to ensure that that protection remains in place and is enhanced so that we can fulfil our commitments.

With Ukraine, we are ensuring that it has the capability to defend itself. That involves training, and the UK has trained more than 20,000 troops in Ukraine. We are also supplying extra capability for naval defences as well as support in areas such as cyber-security and other services.]
