A suspended Labour councillor described far-right protesters as "disgusting Nazi fascists" and said "we need to cut all their throats and get rid of them all", a court has heard.
Ricky Jones, 58, is on trial at Snaresbrook Crown Court charged with encouraging violent disorder during an anti-racism protest in Walthamstow, east London, on August 7 last year.
Jurors were shown a video in which Jones appeared to tell a crowd through a microphone: "They are disgusting Nazi fascists. We need to cut all their throats and get rid of them all."
He also drew his finger across his throat as he spoke to the "tinderbox" crowd.
Prosecutor Ben Holt said: "That clip went viral and came to the attention of the police and others and led to Mr Jones being arrested on the following day on August 8."
He added that Jones used "inflammatory, rabble-rousing language in the throng of a crowd that we will hear described as a tinderbox".
The now-suspended councillor had been told by the Labour Party to stay away from the protest, but turned up anyway, jurors heard.
Opening the case on Monday, Mr Holt said: "Last summer, three young girls were killed at a dance-themed party in Southport.
"There was some hysteria... Some of that grief manifested itself in anger, and regrettably, violence."
The incidents brought out counter-protests, one of which Jones decided to go to, the prosecutor said.
"He attended in the face of considered advice not to do so," Mr Holt added.
The demonstration was organised in response to the nationwide violent disorder that occurred last summer following the fatal stabbings at a children’s dance class in Southport, Merseyside.
Jones, of Dartford, who denies one count of encouraging violent disorder, told police he was "sorry" he made the comments "in the heat of the moment", and had not intended for them to be "taken literally", Mr Holt said.
The councillor also told police he was upset having been sent pictures of National Front stickers that had been left on a train, which had razor blades hidden behind them.
Jones, who has been a borough councillor in Dartford, Kent, since 2019, was suspended by the Labour Party the day after the alleged incident.
The trial continues.
