At least 15 protests are being planned amid a surge of violent disorder in the wake of Monday's mass stabbing in Southport, an investigation has found.
Protests are being planned online in areas including Leeds and Bristol following unrest in recent days that has spread to Manchester, Aldershot, Hartlepool and London, according to the PA news agency.
Prime Minister Sir Keir Starmer said police forces around the country will share intelligence through a new National Violent Disorder Programme as part of their response.
He said: 'These thugs are mobile, they move from community to community, and we must have a police response that can do the same.'
Starmer described the chaotic scenes that unfolded in the aftermath of the stabbing as the 'actions of a tiny, mindless minority' and condemned 'far-right hatred'.
Earlier on Thursday, a 17-year-old appeared in court charged with the murder of three children in the attacks on Monday.
The prime minister said the new national violent disorder programme would help clamp down on violent groups by allowing forces to share intelligence.
He warned: 'We will take all necessary action to keep our streets safe.'
New powers would include shared intelligence and the wider deployment of facial recognition technology.
It would also include more Criminal Behaviour Orders to restrict the movement of offenders and stop them travelling, similar to measures taken against football hooligans.
