A large crowd turned out to support Kate during her first public appearance this year.

But anti-monarchy demonstrators were also depicted arriving at The Mall before the annual ceremony.

One protester, wearing a yellow republican top, was seen waving a flag with the message ‘not my king’, alongside royal supporters holding Union flags.

Republic has previously taken a stand at major royal events, including the king’s coronation last year, during which several activists were arrested.

It supports removing the monarch and replacing him with an elected head of state.

Chief executive Graham Smith said that while he disagreed with the reasons given by police, the restriction was not a “major problem”.

“We have some pretty loud voices,” he said.

Scotland Yard confirmed that the campaign group would be allowed to protest between 8am and 3pm, but without amplified sound.
