Of course, by definition, the Government’s role is negotiating with the parties I have just indicated—the Council, the Commission and the member states—on those measures to which they agree it is possible for us to opt back into. That process, which takes some time, has been put in motion. I will describe where we are a little later but, by definition, the process must be undertaken by the Government. We have been clear that we will come back to Parliament, which will have the opportunity to debate and vote on the package of measures.
As my hon. Friend the Member for Stone (Mr Cash) is well aware, we have indicated the measures on which we wish to opt back in. The discussions are in place with the European Commission and the other member states as to their views—whether or not they wish the UK to opt back in—and any other matters they wish to discuss with us as part of that negotiation.
