A senior Labour minister today defended Sir Keir Starmer's top legal adviser as he faced fury for linking calls for Britain to quit the European Convention on Human Rights (ECHR) to Nazi ideology.

In an astonishing speech last night Lord Hermer, the Attorney General, hit out at MPs and the media for being behind a 'siren song' pushing for Britain to drop international law.

Speaking at a London think tank the former human rights lawyer and close friend of the Prime Minister said such 'songs' had been heard before, citing Nazi ideologist Carl Schmitt, who supported Hitler's policies such as the Night of the Long Knives assassinations.

In a lecture at the Royal United Services Institute, a defence and security think-tank, he said the Labour Government had a 'policy of progressive realism' that means it will never leave international conventions such as the ECHR.

Numerous senior politicians on the Right have called for Britain to leave the convention after it blocked Rwanda deportation flights.
