People from across the UK will be celebrating the anti-monarchy event Republic Day in London, Edinburgh and Cardiff on Saturday.

This is the second Republic Day which was launched last year on the anniversary of the coronation. The event is organised by anti-monarchy campaign Republic.

A rally, protest and festival will be held on Trafalgar Square from midday to 3pm on Saturday May 10th. Smaller events will be held outside Cardiff Castle and on Calton Hill in Edinburgh.

As well as a host of speakers and entertainment Chuck the Rex will be standing tall in the middle of the Trafalgar Square. Chuck is Republic's 15ft dinosaur puppet which last made a public appearance at the Commonwealth Day protest in March.

Speakers will appear on stage and on the screen in London, including Norman Baker, Natalie Bennett, Kelechi Okafor, Sooz Kempner, Abby Tartellin, Grace Blakeley, Graham Smith, Jake Bowers, Jassa Ahluwalia, Peter Tatchell, Floris Müller, Nikita Gill and Yasmin Poole.

There will also be music and entertainment from Teshay Makeda, Nasty Fishmonger and Strawberry Thieves.

Speaking for Republic, Graham Smith said today:

"This is the second Republic Day and is set to be bigger and better than the first. We have more speakers and performers – over thirty – across three cities: London, Edinburgh and Cardiff."

"From humble origins Republic Day has ambitions to grow into an iconic annual event."

"At a time of increasing optimism for the campaign we hope to use Republic Day to showcase the movement, spotlight the issues and celebrate the best of our culture and political traditions."

"Polling shows the monarchy is losing support, with enthusiasm for the royals falling sharply. Unease about the political direction the country is taking and the risks of a weak constitution in uncertain times also opens up new opportunities for the campaign."

"We know that abolishing the monarchy is about more than ridding us of one rotten institution. A republic can give us the tools with which to build a fairer, more equitable and democratic society. In short, it will change the country for good."
