So far, as the right hon. Gentleman says, we have used the United Nations to put pressure on ISIL by making it clear that people should not be providing resources or sanctuary to these people; indeed, they should be cut off. That has been the approach so far. But we do have an opportunity, through the UN, to marshal international support and backing for the view that this ISIL so-called Islamic caliphate is unacceptable and needs to be squeezed out of existence. That is what we should do, and we should aim to get the maximum support through the UN for the measures, right across the board, that are being taken.
