A man has admitted urinating at the Westminster memorial dedicated to PC Keith Palmer.
Andrew Banks, 28, of Stansted, Essex, was photographed during Saturday’s right-wing protests in London.
He was sentenced to 14 days in custody, after pleading guilty to outraging public decency at Westminster Magistrates’ Court.
PC Palmer, 48, was stabbed while on duty during the Westminster terror attack on 22 March 2017.
He was one of five people murdered by Khalid Masood.
The image of Banks was widely shared on social media on Saturday as violent clashes between far-right protesters and police took place in central London.
Prosecutor Michael Mallon said Banks, a Tottenham Hotspur fan, was in central London to “protect statues”, but admitted he did not know which statues.
He was said to have drunk 16 pints during Friday night into Saturday morning, and had not been to sleep.
Banks contacted police after being confronted by his father, the court heard.
His counsel Stuart Harris said his client was “ashamed by his action”, and had mental health issues.
The act was widely condemned at the time by politicians including MP Tobias Ellwood, who gave first aid to PC Palmer as he lay dying in the grounds of Parliament.
