Dr Julian Lewis: Would it not send a very bad signal to President Putin when he is eyeing up the Baltic States if Britain fell below the NATO recommended minimum of 2% of GDP going on defence? Will the Prime Minister give an undertaking not to do that as long as he is in office?

[The Prime Minister: We have set out our plans for this Parliament, and we will have to set out our plans for the years ahead at the next election. As I said, we have maintained a £33 billion defence budget – one of the top five in the world. The most important message for the Baltic States is that they are full members of NATO. I think they are very grateful for that when they see the destabilisation that is taking place in other parts of the world. We need to guarantee to them that being full members of NATO means just that.]
