Brexit: How would you vote now?
Tony Blair has called on pro-Europeans to form a new cross-party movement to persuade the public they were wrong to vote to leave the European Union.
In a speech, the former Prime Minister and Sedgefield MP said "progressives" should make it their "mission" to reverse the outcome of the referendum last June.
Speaking at the London headquarters of Bloomberg, where David Cameron first set out his plan for an in/out vote on Britain's EU membership, Mr Blair rejected the idea that leaving was now "inevitable".
He said that when people had voted last year, they had not understood the full cost of withdrawal, including the potential break-up of the UK with Scottish independence "back on the table" and with renewed credibility.
Foreign Secretary Boris Johnson, who led the official Vote Leave campaign in the referendum - dismissed Mr Blair's "condescending campaign" to reverse the will of the people, insisting Brexit would be a "spectacular success".
Mr Johnson accused the former Prime Minister of "insulting the intelligence of the electorate" in arguing they had voted the wrong way.
