Watch: Anti-monarchy protesters gather in London as King Charles is crowned

Watch as anti-monarchy protesters gather in central London on the day of King Charles III's coronation.

Republican activists have been chanting "not my King" during a demonstration in Trafalgar Square as royal fans lined the streets of central London to take part in celebrations.

Some protesters were arrested hours before the ceremony took place as police seized lock-on devices.

The Metropolitan Police confirmed that four people were arrested on suspicion of conspiracy to cause a public nuisance on St Martin’s Lane.

A number of breaching-the-peace arrests were made in the area of Carlton House Terrace and a further three arrests in the Wellington Arch area on suspicion of possessing articles to cause criminal damage, the force said.

Footage posted on Twitter showed police using their powers under the new Public Order Act, as chief executive of anti-monarchy group Republic, Graham Smith, was among those apprehended near Trafalgar Square.

Demonstrators in yellow “Not My King” T-shirts, including Mr Smith, had their details taken.
