EU reform is “not achievable” and the government has not delivered on its promises of change, London mayor Boris Johnson has said.
David Cameron has said he has secured a commitment to exempt the UK from “ever closer union”.
But Mr Johnson told the BBC’s Andrew Marr the EU wanted a “superstate into which we would inevitably be dragged”.
Instead, he said the UK had a “once in a lifetime opportunity” to make its own relationships with other nations.
Speaking on the Andrew Marr Show, Mr Johnson said the outcome of Mr Cameron’s negotiations on EU reform led to his decision to support a vote to leave the EU in June’s referendum.
“We were told were going to get wholesale changes,” he said.
“Anybody looking at the agreement that we have before us now would be in no doubt that this is not fundamental reform.
“The next item on the agenda is the further evolution of what was a common market into this superstate into which we would inevitably be dragged.”
In February the government announced it had reached a deal to set out the UK’s relationship with the EU. The prime minister had wanted an opt-out of the EU’s founding ambition to forge an “ever closer union”.
The final deal said the UK “is not committed to further political integration into the European Union” and that this would be incorporated into EU treaties.
The prime minister said in February: “Let me put this as simply as I can: Britain will never be part of a European superstate.”
