Hundreds of thousands in UK urge new vote on Brexit

Hundreds of thousands of people turned out to march in the streets of London over the weekend, calling for another EU referendum. It's being described as one of the biggest demonstrations in British history, on par with the 'Stop the War' march in 2003. The protests come as pressure mounts on Prime Minister Theresa May to resign in order to help her Brexit deal pass. Our correspondent in London is Olly Barratt.
