The march of the popular vote is an insult to democracy: we have already had the popular vote
Andrew Bridgen said that the popular vote was led by a group of people who simply want to "annul the democratic decision made in the referendum of the EU 2016".
The Deputy of the Conservative Party for North West Leicestershire said that a second vote on the same issue "would undermine democracy" before adding that the British have already voted.
He told Express.co.uk: "If there were another referendum, people would challenge all the votes of a single majority, which would be the best of the three, the best of five?
The Tory deputy also said that making countries have another referendum was a "European Union tactic".
"They have used it to nullify democratic votes in other countries and we must make sure they do not succeed in Britain," he said.
Mr. Bridgen stated that some supporters of Remain in their own constituency are now supporting the Permit because of the way in which the European Union has treated the United Kingdom in the negotiations.
He said: "Even in my seat, people in North West Leicestershire, some people who supported Remain are now supporting Leave because they have seen how the EU has been treating us, we would be a full doormat if we returned to the EU.
"There simply can not be another vote, it would be the end of democracy."
Michael Fabricant, a conservative deputy for Lichfield, said that those who marched by a popular vote simply did so because they did not like the result of the EU referendum in 2016.

"They are marching to cancel the vote of the people because they do not like the result." What hypocrisy!
