Downing Street is to hold an emergency response meeting after nearly a week of violence and disorder in towns and cities across England.
More than 150 arrests were made at the weekend, with Sir Keir Starmer promising those involved would face "the full force of the law".
Today's meeting will involve relevant ministers and police representatives, civil servants, intelligence officers and other appropriate members.
Sunday evening saw more violence and unrest in Rotherham, Middlesbrough, Bolton and other parts of the country.
A Holiday Inn Express at Tamworth, which houses asylum seekers, was also targeted as missiles were launched through windows and fires set in the building.
Sir Keir, who was made Prime Minister a month ago today, warned those taking part would "regret" it.
In a televised address on Sunday evening he said: "People in this country have a right to be safe, and yet we've seen Muslim communities targeted, attacks on mosques," the prime minister said.
"Other minority communities singled out, Nazi salutes in the street, attacks on the police, wanton violence alongside racist rhetoric, so no, I won't shy away from calling it what it is: far-right thuggery."
There has also been suggestions that courts could sit 24 hours a day to fast-track prosecutions, like they did during the riots in 2011.
