Former Attorney General on 'pointless' sovereignty law

Dominic Grieve says primacy in interpretation of European law is given to the Court of Justice in Luxembourg and "it's difficult to see how any piece of legislation can alter that without us being in breach of the treaties".

"At the end of the day the buck stops somewhere. And the treaty of accession, and our own legislation, makes quite clear that it is the Court in Luxembourg which has the last word," said the former attorney general.

His comments to Martha Kearney on BBC Radio 4's The World at One were in response to David Cameron's suggestion that a new law could be passed to reassert the power of UK Parliament law over the EU.
