Interesting bit from the guardian
If Boris Johnson looked downbeat yesterday, that is because he realises that he has lost.
Perhaps many Brexiters do not realise it yet, but they have actually lost, and it is all down to one man: David Cameron.
With one fell swoop yesterday at 9:15 am, Cameron effectively annulled the referendum result, and simultaneously destroyed the political careers of Boris Johnson, Michael Gove and leading Brexiters who cost him so much anguish, not to mention his premiership.
How?
Throughout the campaign, Cameron had repeatedly said that a vote for leave would lead to triggering Article 50 straight away. Whether implicitly or explicitly, the image was clear: he would be giving that notice under Article 50 the morning after a vote to leave. Whether that was scaremongering or not is a bit moot now but, in the midst of the sentimental nautical references of his speech yesterday, he quietly abandoned that position and handed the responsibility over to his successor.
