In the first part of efforts to renegotiate Britains relationship with the European Union, ministers will announce plans to claw back the powers. Theresa May, the Home Secretary, will give MPs details of proposals to opt out of 133 EU measures covering justice, home affairs and the police including the controversial European Arrest Warrant by next spring. Some of the measures that are seen to be in the national interest will then be opted back into, in a complex process, but more than two thirds will disappear permanently from British law, The Sunday Telegraph has learnt.
