Dr Julian Lewis: Mr Putin knows that NATO will not start world war three to defend Ukraine, but has he been made aware of precisely what non-military sanctions will follow? For example, are Finland or Sweden likely to proceed with an application to join NATO, as has been suggested?

[The Secretary of State for Defence (Mr Ben Wallace): First, there is a basket of sanctions that are prepared both by the United Kingdom and the United States. Indeed, the EU is addressing and formulating a package and, obviously, Sweden and Finland would be part of that. I cannot speak for Sweden and Finland about whether they would join NATO. One of the fundamentals of NATO is the open door policy. We have been clear on that, but, as I have said, I am even more clear that defending a country to choose is actually more important often than what it chooses. We enhance and work our relationship with Finland and Sweden through the joint expeditionary force, which is 11 nations – Scandinavian and Nordic, and Britain – working together and exercising together in the defence world. That is brilliant: it binds together the EU, NATO and other members to make sure that we can deter by being as professional as possible with our armed forces.]
