Voters “cannot trust” David Cameron and George Osborne to honour their promises on Europe, Michael Gove and Boris Johnson have warned in an extraordinary attack on their government colleagues.

The leaders of the Vote Leave campaign declare that the Prime Minister has put the British economy in “severe danger” by giving away the UK’s veto during talks in Brussels earlier this year.

They say Mr Cameron’s renegotiation of Britain’s European Union membership leaves Britain “dangerously and permanently exposed” to being forced to hand over more money and accept “damaging new laws”.
