'Who cares what he says? He's going. Bye Bye': Barack Obama's warning there will be no special trade deal for post-Brexit Britain is laughed off by leading Tories

Barack Obama (pictured) stepped up his controversial cautions about Brexit - and suggested Britain's relationship with the United States risked 'unravelling' in the wake of the referendum. 


Mr Obama caused anger at the height of the referendum campaign then he used a visit to London to warn voters that the UK would go to 'the back of the queue' in negotiating a new trade deal if it opted for Brexit. Speaking after an hour-long meeting with Theresa May at the G20 summit (also pictured) in China, Mr Obama bridled at suggestions he had threatened to 'punish' Britain for leaving the EU. Leading Tories like Iain Duncan Smith (inset) have said Obama's words mean little because he is to depart in the new year.
