I am sure that I do not need to remind my hon. Friend, given his attention to detail in these matters, that were we not voting and deciding to opt out of the number of measures we are proposing to opt out of, we would find ourselves subject to all these measures, all of which would be subject to the European Court of Justice.
Let me be clear: this should not be a one-off event before usual service resumes. This Government have made sure that never again will a Prime Minister sign away sovereignty in a European treaty without a referendum. We in the Conservative party have made clear our intent to negotiate a new relationship with the European Union which will then be put to the British people in an in/out referendum. Of course, it is too early to be specific about the changes we will seek in that negotiation, but I am clear that the decision to opt out of these justice and home affairs measures in 2014 does not leave us with the ideal settlement—far from it. Significant problems still need to be addressed, such as the interpretation and enforcement of free movement rules, the creative way in which measures agreed by nation states are subsequently interpreted, and the jurisdiction of the European Court of Justice.
