A Suffolk woman will face trial after being charged with criminal damage to the main sign outside New Scotland Yard in London.

Lora Johnson, 38, of Keens Lane, Reydon, near Southwold, appeared before Westminster Magistrates' Court.

The well-known New Scotland Yard sign was covered in yellow paint and demonstrators also blocked the road in front of the Metropolitan Police's headquarters during Just Stop Oil's action on Friday.

Protesters glued themselves to the floor at the demonstration outside the police HQ on Victoria Embankment.

The prosecution says £4,750 has been spent trying to remove the paint from the sign and the ground under it.

Johnson pleaded not guilty to causing criminal damage to the rotating New Scotland Yard sign.

District judge Tan Irkam released Johnson on bail on the condition she does not have paint or adhesive materials in a public place.

Her trial will take place on November 23 at the City of London Magistrates' Court in Queen Victoria Street, London.

A spokesman for the Metropolitan Police said a total of 28 arrests were made in relation to the protests in central London on Friday.

The spokesman added that 25 people have been bailed pending further enquiries.

Also before the court on Saturday morning were two women charged in relation to soup being thrown on Vincent Van Gogh's Sunflowers painting at the National Gallery in Trafalgar Square.

Anna Holland, 20, from Newcastle, and Phoebe Plummer, 21, from Lambeth, south-west London, both pleaded not guilty to criminal damage to the frame of Van Gogh's painting, causing damage to the value of less than £5,000.

Prosecutor Ola Oyedepo alleged the pair threw an "orange substance" knowing there was a "protective case" over the actual painting, though damage was caused to the frame.

They will stand trial on December 13 at City of London Magistrates' Court.
