In London this weekend, hundreds of thousands of people took to the streets to oppose the Brexit vote.
Sadiq Khan, the London Mayor, was one of the speakers who took to their expensive staging. He had the temerity to shout about the "will of the people."
But 17.4 million people have already voted to leave the EU. Is it really possible their democratic vote will be overturned on account of one rally, no matter how large?
