The government has rejected an online petition, signed by more than 4.1 million people, calling for a second EU referendum to be held. An email to those who signed the petition said the prime minister and government had “been clear that this was a once-in-a-generation vote”.
It said the decision “must be respected”, and “we must now prepare for the process to exit the EU”. The UK voted to leave the EU by 52% to 48% in the referendum on 23 June.
Meanwhile, US President Barack Obama said he believed the UK would quit the European Union despite speculation the vote for Brexit could somehow be reversed.
“I think we have to assume that a referendum having been passed with a lot of attention, a lengthy campaign and relatively high participation rates is going to stick,” he told a news conference at the end of a Nato summit in Warsaw.
