Hundreds of people have travelled from Wales to London in order to join a protest calling for a second referendum on Boris Johnson's new Brexit deal.
Effigies of the Prime Minister, and pets draped in EU flags have been pictured at the People's Vote march to Westminster.
One group of protesters were seen near Downing Street, pulling a float depicting top aide Dominic Cummings using Mr Johnson as a puppet.
At the start of the march route, morris dancers, some wearing Morris Against Boris t-shirts, performed a routine before the protesters set off.
They are due to walk through central London to Parliament Square, where protesters will hear speeches from politicians and celebrities who support a confirmatory vote.
Liberal Democrat MP and People's Vote supporter, Chuka Umunna apologised for missing the march, and told campaigners "we are making the same argument in the House of Commons right now!"
People's Vote organisers are also asking people to sign a letter to Mr Johnson, EU leaders, MPs, and MEPs, asking them to allow "the chance to check whether we want to proceed with Brexit".
In an email to supporters this morning, shadow Brexit secretary Sir Keir Starmer said the letter "asks them to honour our shared democratic values, it asks them not to turn away from us now and deny us the chance for a final say.
"Add your name to the letter now and send a message to the powerful."
Meanwhile, Brexit supporters were campaigning in Manchester.
A small group of protesters are preparing to take part in the march for democracy in the city on Saturday afternoon.
