Those involved in the riots could expect to be brought before the courts, Starmer said, noting that what he called “significant sentences” had already been handed out.
“That is a very important part of the message to anybody who is thinking about getting involved in further disorder,” he told reporters during a visit to a police command centre in London.
It is not clear how many far-right gatherings are planned or if they will go ahead. There are around 40 counter-protests due on Saturday, according to the Stand Up to Racism group.
The National Police Chiefs’ Council (NPCC) said 6,000 public order trained officers would remain on duty over the weekend.
“While the previous two nights have been a welcome break from the appalling scenes of the last week, and may have reached a turning point, we are by no means complacent,” Chief Constable Gavin Stephens, NPCC Chair, said.
“We are working hard to bring this disorder to an end, but arrests are just getting started.”
Almost 600 people have been arrested so far for involvement in, or online encouragement of, attacks on Muslim, immigration and other sites as well as police since late last month, with a 13-year-old among those charged.
Data released on Friday by the Justice Ministry showed that more than 150 of those charged have already appeared in court. Dozens have already been jailed with cases fast-tracked through the justice system and more are due to be sentenced on Friday.
Charges have also been brought against people involved in counter-protests.
Prosecutors said a local councillor, who was suspended by Starmer’s Labour Party on Thursday after footage emerged of him calling for people to cut the throats of “disgusting Nazi fascists”, had been charged with encouraging violent disorder and would appear at court on Friday.
