More than 100 people were arrested after protestors hurled beer cans and glass bottles at police in Whitehall.

Prime Minister Sir Keir Starmer is now set to hold an emergency meeting with senior police officers after unrest in London, Hartlepool and Manchester yesterday evening (July 31).

Demonstrators wearing England flags and waving banners saying “enough is enough” and “stop the boats” gathered outside Downing Street in the wake of the killing of three young girls in a knife attack in Southport.

Social media posts falsely claimed that the attack was carried out by a Muslim asylum seeker who crossed the Channel in a small boat.

The angry scenes also included loud chants of: “We want our country back” and: “Oh Tommy Robinson”, referring to the right-wing activist.

One man wore a shirt with the slogan: “Nigel Farage for Prime Minister, Tommy Robinson for Home Secretary”.

Flares were also launched at the statue of Winston Churchill in Parliament Square.

The original conditions imposed on the protest said that those gathering had to disperse by 8.30pm, and protestors were told to remain in a narrow area opposite Downing Street.

The Metropolitan Police said they made arrests for offences including suspected violent disorder, assault on an emergency worker and breach of protest conditions.

Superintendent Neil Holyoak said: “Following the tragic events in Southport, it is understandable the public have strong feelings about this shocking incident - but the subsequent violent, unlawful disorder that unfolded was completely unacceptable and driven by misinformation.”

He added: “I urge everyone to exercise their right to protest calmly and within the law.”

A 17-year-old boy has now been charged with the murders of the three girls in Stockport.

Alice Dasilva Aguiar, nine, Elsie Dot Stancombe, seven, and Bebe King, six, were fatally stabbed on Monday when a knifeman entered a Taylor Swift-themed dance class on Hart Street in Southport, Merseyside.

Eight other children suffered knife wounds – with five of them in a critical condition – while two adults were also critically injured.

The 17-year-old has been remanded in custody to appear on Thursday at Liverpool Magistrates’ Court.
