Downing Street has confirmed there will be an emergency response meeting on Monday after more than 150 people were arrested following violent disorder in UK towns and cities over the weekend.

It comes after Sir Keir Starmer condemned an attack on a hotel housing asylum seekers in Rotherham and promised those involved in unrest would face “the full force of the law”.

Police responded to violent scenes in Tamworth, Middlesbrough, Hull and other parts of UK on Sunday.

The Cobra meeting will come after a sixth day of escalating violence following the fatal stabbing of three young girls in Southport last week.

Cobra meetings, or Cobr meetings as they are often also called, are named after Cabinet Office Briefing Room A on Whitehall.

It is an emergency response committee, a get together of ministers, civil servants, the police, intelligence officers and others appropriate to whatever they are looking into.

Monday’s meeting of the emergency committee will be intended to provide the government with an update on the violence over the weekend and the response in the coming days. It will involve relevant ministers and police representatives.

Sources have suggested this should be seen in the context of meetings that have already taken place, such as one between the prime minister and police chiefs last Thursday, and a meeting of senior ministers on Saturday.

During the prime minister’s televised address on Sunday, he warned those involved that they will “regret” taking part.

“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.”

In a statement, the Home Office offered mosques greater protections as part of a new process, under which it said “rapid security” deployment can be requested in order to allow a return to worship as fast as possible.

In Rotherham, at least ten police officers were injured with one left unconscious after anti-immigration demonstrators threw planks of wood at officers and sprayed them with fire extinguishers, South Yorkshire police said.

Some members of the group smashed windows to gain access to the Holiday Inn Express and a large bin was set alight.

The officer knocked unconscious suffered a head injury, the force said, adding that at least two others had suspected broken bones.

Hotel employees and residents, some of whom are asylum seekers, were “terrified”, but no injuries were reported, police said.

Home Secretary Yvette Cooper called the scenes “utterly appalling” and said police have government backing to take “the strongest action”.

At a second hotel in Tamworth, Staffordshire, officers said they had to deal with “violent acts of thuggery” on Sunday evening.

One officer was injured at the site as people threw missiles, smashed windows, and started fires, Staffordshire Police said.

Meanwhile, a group of rioters in Middlesbrough smashed the windows of houses and cars and hurled objects at officers.

In Dorset, 600 people from opposing sides gathered on the seafront in Weymouth. Officers said there had been a “small number of low-level incidents”, with one man arrested for a public order offence.

And in Bolton, anti-immigration protestors were confronted by a group of up to 300 masked people shouting “Allahu Akbar” – or “God is greatest”.

Greater Manchester Police issued a Section 60AA order in the town which requires people to “remove face coverings used to disguise or conceal their appearance”.

The violence followed similar scenes of unrest in Southport, Belfast, Hartlepool, Hull, Liverpool, Stoke-on-Trent, Nottingham, Sunderland and elsewhere earlier in the week.

Sir Keir indicated the response to the violence could mirror elements of how the 2011 riots were handled, at which time he was director of public prosecutions.

“We do have standing arrangements for law enforcement which means that we can get arrests… and convictions done very quickly,” he said.

“I myself was part of that in 2011 when I was director of public prosecutions, and I’m determined we will do whatever it takes to bring these thugs to justice as quickly as possible.”

Ministers have suggested that courts could sit 24 hours to fast-track prosecutions – as they did in 2011 – while police forces have measures in place to draft in extra officers to tackle potential unrest.
