Millions of Brits voted in the EU referendum across the UK, and a slight majority preferred to leave the EU. The country's decision to leave the EU was won by a narrow margin. 52 percent voted in favor of leaving the EU, while 48 percent voted to stay in the EU.

A petition demanding a second EU referendum has been gaining traction on the Internet and temporarily crashed the House of Commons website due to a high volume of simultaneous visits. The petition has gained nearly 700,000 signatures, which is seven times more than required to raise the issue in Parliament.

The petition calls upon the government to enact a rule to conduct a second round of referendum if the first round fails to get a clear majority.

"We the undersigned call upon HM Government to implement a rule that if the remain or leave vote is less than 60% based a turnout less than 75% there should be another referendum," it states.

Scotland voted overwhelmingly to stay in EU (62 percent for 'In' and 38 percent for 'Out').

After Scotland, London was the province where a majority of people (60 percent) wanted to remain in EU, followed by Northern Ireland (56 percent).

The voting has led to speculations that there might be another Scottish referendum coming soon to decide on its exit from UK, because a majority of its citizens want to remain in EU.

In London, over 100,000 people signed a petition asking London's mayor, Sadiq Khan, to declare independence from the UK and apply to join the EU.

"London is an international city, and we want to remain at the heart of Europe," the petition says. "Let's face it - the rest of the country disagrees. So rather than passive aggressively vote against each other at every election, let's make the divorce official and move in with our friends on the continent."

"This petition is calling on Mayor Sadiq Khan to declare London independent, and apply to join the EU - including membership of the Schengen Zone."

Meanwhile, nationalists in Northern Irealand also joined the Londoners and Scotts in floating the idea of a vote on Irish reunification.

West Midlands (59.3 percent), East Midlands (58.8 percent), and North East (58 percent) were the regions where most of the people voted to depart from EU.

Prime Minister David Cameron announced that he will step down as chief of the country after the UK decided to leave the EU. He had wanted the country to remain in EU, and had campaigned for the cause.

He said that he will remain as a caretaker till UK elects a new Prime Minister.

"I will do everything I can as prime minister to steady the ship over the coming weeks and months," he said. "But I do not think it would be right for me to try to be the captain that steers our country to its next destination."

Archbishop of Canterbury, Justin Welby, and Archbishop of York, John Sentamu, issued a joint statement after the UK decided to leave EU.

"The vote to withdraw from the European Union means that now we must all reimagine both what it means to be the United Kingdom in an interdependent world and what values and virtues should shape and guide our relationships with others," the statement reads. "As citizens of the United Kingdom, whatever our views during the referendum campaign, we must now unite in a common task to build a generous and forward looking country, contributing to human flourishing around the world. We must remain hospitable and compassionate, builders of bridges and not barriers."

"As those who hope and trust in the living God, let us pray for all our leaders, especially for Prime Minister David Cameron in his remaining months in office. We also pray for leaders across Europe, and around the world, as they face this dramatic change. Let us pray especially that we may go forward to build a good United Kingdom that, though relating to the rest of Europe in a new way will play its part amongst the nations in the pursuit of the common good throughout the world," it concluded.
