Input: Former British Prime Minister Tony Blair  on Thursday warned voters that time was running out to reverse Brexit  a folly he said would torpedo Britainâs remaining clout and be regretted for generations to come.
 Blair   Labour prime minister from 1997 to 2007  said Britain would be poorer  weaker and warned that May had solved none of the problems over Northern Irelandâs post-Brexit status.
âWe are making an error the contemporary world cannot understand and the generations of the future will not forgive â  Blair  said in an article published on  his  website on Thursday.
Leaving the European Union was once far-fetched: just over 15 years ago  British leaders such as  Blair  were arguing about when to join the euro  and talk of an EU exit was the reserve of sceptics on the fringes of both major parties.
 Blair  has repeatedly called for reversing Brexit  echoing other opponents of Brexit such as French President Emmanuel Macron and billionaire investor George Soros  who have suggested that Britain could still change its mind.
Supporters of Brexit dismissed  Blair  and said  he  was undermining both the British negotiation and the will of the people.
â Blair  and  his  elitist gang are damaging our negotiating strength  thus damaging our national interest by their continuing efforts to undermine democracy â said Richard Tice  who helped found one of the two Leave campaign groups.
 Blair  is unpopular in Britain for  his  decision to back then-U.S. President George W. Bushâs 2003 invasion of Iraq and the justification  he  used for going into a war that cost the deaths of 150 000 Iraqi civilians and 179 British soldiers.
But  he  has become increasingly outspoken about Brexit.
 He  implored  his  Labour Party  which is now led by socialist Jeremy Corbyn  to join the fight to stop Brexit.
âMake Brexit the Tory Brexit. Make them own it 100 percent â  Blair  said. âIf Labour continues to go along with Brexit and insists on leaving the Single Market  the handmaiden of Brexit will have been the timidity of Labour.â
