A TORY government would deliver an ultimatum to European judges that Britain must be allowed to flout their human rights rulings, or it would quit the system.

Justice Secretary Chris Grayling said the "mission creep" by the Strasbourg courts had become intolerable and it would have to accept becoming an "advisory" body.

Mr Grayling fleshed out the Conservative position after David Cameron told the party's conference that he would no longer put up with meddling on issues such as whether prisoners should be able to vote.

"We can no longer tolerate this mission creep," he said.

"What we have effectively got is a legal blank cheque, where the court can go where it chooses to go."
