In the course of responding to the conflict in Ukraine we have been encouraged by the attitude and decisions of our friends within the EU. Very constructive measures have been taken and there has been a manifest level of co-operation and recognition of what I said earlier—that this is a threat that affects us all. It may be that an individual political leader in an individual European country has reservations about sanctions. It is for the other countries, whether inside or outwith the EU, to explain that the evidence is there that sanctions work and are beginning to bite Putin where it matters. That is a very powerful argument to advance.
