A man has been charged after someone was photographed apparently urinating next to the memorial dedicated to Pc Keith Palmer, the Metropolitan Police has said.
Andrew Banks, 28, of Stansted, Essex, has been charged with outraging public decency.
He will appear in custody at Westminster Magistrates’ Court on Monday.
Pc Palmer was stabbed to death in the grounds of Parliament by Khalid Masood in 2017.
On Saturday, a man was seen to apparently urinate next to the memorial during far-right protests in London.
The incident, which was caught on camera, sparked outrage, with MP Tobias Ellwood describing the incident as "abhorrent".
Mr Ellwood, who gave first aid to Pc Palmer as he lay dying, called on the man to come forward.
Home Secretary Priti Patel also hit out about the "absolutely appalling and shameful incident".
She said: “We have seen some shameful scenes today, including the desecration of Pc Keith Palmer’s memorial in Parliament, in Westminster Square, and quite frankly that is shameful, that is absolutely appalling and shameful.”
