EU referendum: Boris Johnson accuses Barack Obama of 'hypocrisy'

The London mayor, who backs EU exit, told the BBC the Americans "wouldn't dream of sharing [their] sovereignty" as the UK had done.
The US president is expected to repeat his support for Britain's EU membership when he visits the UK next week.
Backers of Remain dismissed Mr Johnson's remarks as "nonsense", citing US membership of Nato and trade bodies.
The White House has indicated Mr Obama is ready to offer his view on the issue but will stress the decision is for UK voters.
Speaking in Washington, Chancellor George Osborne said it was the "overwhelming view" of foreign governments and international institutions such as the IMF and Nato that the UK should remain.
Backing from Mr Obama could boost Prime Minister David Cameron's efforts to persuade the country to vote to remain in the EU in the 23 June referendum.
Asked about the US president, the London mayor said everything about the history of the US suggested they would never share sovereignty.
"I don't know what he is going to say but, if that is the American argument then it is nakedly hypocritical. The Americans would never dream of it," he told the BBC.
'Absolutely bizarre'
"I think that President Obama has got a perfect right to make any intervention that he wants. Indeed I welcome the views of everybody in this debate.
"I just find it absolutely bizarre that we are being lectured by the Americans about giving up our sovereignty and giving up control when the Americans won't even sign up to the international convention on the law of the seas, let alone the International Criminal Court."
Labour MP Stephen Kinnock dismissed Mr Johnson's comments as "utter nonsense".
"The last time I checked, the United States was a member of Nato. You look at article five of Nato, it says any attack on a Nato member is an attack on all. You couldn't have a greater pooling of sovereignty than that," he said.
"The United States is a member of the WTO [World Trade Organization] and a range of other international organisations. We pool our sovereignty in order to make ourselves stronger."
