Except many signing are not even British.
Via BBC:
A petition calling for a second referendum on UK’s membership of the EU has gained more than one million signatures following the vote to leave.
The petition will be considered by Parliament as it has passed the required 100,000 threshold.
The UK voted to leave the EU by 52% to 48% in Thursday’s referendum but the majority of voters in London, Scotland and Northern Ireland backed Remain.
David Cameron previously said there would be no second referendum.
On Friday he said he would stand down as prime minister by October following the leave result.
The petition, set up by William Oliver Healey, states: “We the undersigned call upon HM Government to implement a rule that if the Remain or Leave vote is less than 60%, based on a turnout less than 75%, there should be another referendum.”
