In a letter to The Telegraph, more than a hundred Tory MPs called on the Prime Minister to "opt out" of 130 EU laws over the next two years:

"SIR – The EU Commission's ambitions for a pan-European code of Euro Crimes highlight how Europe should be about co-operation rather than control. We need practical co-operation to fight terrorism, drugs, human trafficking and other cross border crimes – not harmonisation of national criminal laws.

We do not wish to subordinate UK authorities to a pan-European Public Prosecutor. We do not want to see British police forces subjected to mandatory demands by European police under the European Investigation Order. We have deep concerns about the operation of the European Arrest Warrant for our citizens. We want the UK Supreme Court to have the last word on UK crime and policing, not the European Court of Justice.

The recent study by Open Europe offers a pragmatic alternative. Britain should exercise its "opt out" from 130 measures under the EU's crime and policing plan by 2014. The UK would retain the right to opt back in to any specific policies deemed vital on a case-by-case basis. Yet, as British co-operation with Norway after its recent terrorist attacks and our longstanding intelligence relationship with the US shows, we do not have to cede democratic control with close partners in order to co-operate effectively with them.

We should maintain our national standards of justice and democratic control over crime and policing – but let other nations integrate more closely if they wish."
