More than half a million people went to a demonstration in London demanding a ” second referendum” on Brexit .
British Prime Minister Theresa May previously ruled out the possibility of holding such a referendum. At the same time, the protesters are supported by deputies of the largest parties of the British Parliament.
According to opinion polls, if the second referendum was held, the majority would have voted to remain part of the European Union.
The UK should withdraw from the EU on March 29, 2019.
