The Conservative MP is known for his upper-class mannerisms and traditionalist views
The demonstration was dubbed the 'March for a People's Vote' and speakers at the event will included Liberal Democrat leader Sir Vince Cable, Tory rebel Anna Soubry, Labour MP David Lammy and Green Party’s Caroline Lucas.

"Together we must stand up, demand our voices are heard, demand a people’s vote."
Crowds were furious at Labour Party leader Jeremy Corbyn for not attending the event, as he was in the Middle East, visiting Jordan refugee camps.

The prominent Tory backbencher said Remainers would have to “wait a generation” before being granted another EU vote.
