Treaty on the Functioning of the EU

My hon. Friend is right in that rejoining measures means that they will come under the jurisdiction of the European Court of Justice, which is why we have given such careful thought and consideration to the list of measures we are seeking to rejoin, but it is possible for this Parliament to made decisions in UK law that change the way the European arrest warrant operates and give us some of the safeguards that many Members of this House feel other EU member states have had, for example in relation to proportionality. As I said in my statement, I am only sorry that the previous Labour Government did not do that when they had the opportunity.
