A petition calling for a second EU referendum has topped TWO MILLION signatures - more than doubling the highest signed in parliamentary history. The popular petition, which was started just one day ago, attracted so many signatures when it first opened that the government's website crashed. The enormous surge followed the initial 100,000 signatures which were created in a bid to get London Mayor Sadiq Khan to declare the capital as independent. Protesters are hoping that Khan will call for London to be classed separately from the UK and therefore be able to apply to join the European Union.
