A petition for the United Kingdom government to hold a second referendum on Brexit caused the House of Commons website to crash soon after the country, in a historic ballot, voted to leave the European Union. By Friday evening, more than 2,00,000 signatures were on the the petition, with a majority from London, which had backed remaining in the EU, reported The Guardian.

The UK on Thursday had voted on whether it would remain with or leave the EU. On Friday, the ‘Leave’ camp won with around 51.9% of votes. The move caused world markets to crash and the British currency to slump to its lowest in 31 years.

If a petition has more than 1,00,000 signatories, it will be considered in the British parliament. The ‘Leave’ camp won millions of votes across the north of England, the Midlands, the South East and Wales, while ‘Remain’ garnered votes in Scotland and London. Scotland, which voted to remain part of the UK in a recent referendum, has said it hopes for a future as part of the EU.

Prime Minister David Cameron, a vocal ‘Remain’ supporter, announced his resignation following the Brexit results on Friday.
