EU Justice and Home Affairs Measures

I thank the Home for giving way to me a second time. She has made two cases—the reason for opting in and what would happen if we went back to the 1957 protocols—but there were other choices. A couple of years ago, there was the chance to try to have a bilateral treaty with the EU, or indeed individual member states within it. Equally, as the treaties stand, there are transitional arrangements under which the current arrangements could continue. Could she comment on those? I know that the commonly held view in her Department was that the transitional arrangements would be quite short, but I have gathered from the European Commission that they could go on for quite some time. I would appreciate her view on that.
