Dr Julian Lewis: Have the arrangements we have put in place for the safe withdrawal of troops and especially heavy equipment from Afghanistan by the end of this year in any way been affected by the tension that has arisen between us and Russia?

[The Prime Minister: We have not received any information that would lead us to think that. If we are going to take steps – diplomatically, politically and, potentially, economically – we should take them because it is the right thing to do. We should recognise that there may be consequences from some of those things. There could be consequences for the City of London and some European defence industries, or for energy or other interests around Europe. However, we should proceed knowing that what we are doing is sensible, legitimate, proportionate, consistent and right.]
