Sir Keir Starmer looks set to hold an emergency meeting with senior police officers in Downing Street following violent scenes across England yesterday.
The Prime Minister will look to ease tensions after unrest in London, Hartlepool and Manchester.
Southport, where three children were killed in a brutal stabbing, also witnessed violence.
More than 100 people were arrested in London as demonstrators lobbed beer cans and glass bottles at police.
A group of angry protesters chanted: “We want our country back.”
Eight people were also arrested in Hartlepool, Cleveland Police has confirmed.
Starmer is expected to praise officers for their “bravery” in dealing with the incident in Southport and its aftermath.
He will also encourage them to use their powers to “stop mindless violence in its tracks”.

Starmer fears Badenoch the most, Labour bigwig claims

Sir Keir Starmer fears Kemi Badenoch more than any other Tory leadership hopeful, Labour Lord Peter Mandelson has claimed.
The Labour grandee, who voices much support for the Prime Minister, claimed the ex-Business Secretary’s readiness to call out “wokery” sets her apart from her leadership rivals.
Mandelson said: “She is not afraid to speak her mind (although an occasional filter might be handy) or to call out the sort of ‘wokery’ many voters dislike. I noticed my companions turning in her direction.”
However, the former European Commissioner for Trade also warned Tory fortunes could get even worse.
He wrote: “Next time, when people have got used to a Labour Government and grown to like Keir Starmer’s unpretentious style, his current vote-share may turn into a floor rather than a ceiling.
“Conservatives should not assume that things cannot get worse for them.”
