Sir Keir Starmer has warned rioters will feel the "full force of the law" after convening yet another Cobra meeting tonight.
The Prime Minister gathered top officials as an eighth day of violent unrest looms.
Starmer said: "The Cobra meeting was to coordinate our response to the disorder and I made it very clear on a number of occasions that those involved will feel the full force of the law."
The Prime Minister, who confirmed more than 400 people have been arrested and 100 charged so far, added: "That should send a very powerful message to anybody involved, either directly or online, that you are likely to be dealt with within a week and that nobody, but nobody should be involving themselves in this disorder."
Starmer warns rioters will feel 'full force of the law' as he addresses nation following emergency Cobra meetingPAThe criminal justice system is expected to provide a "robust and swift" response when it comes to punishing rioters.
James Nelson, 18, became the first rioter to receive a custodial sentence after the Bolton boy pleaded guilty to causing criminal damage on Sunday.
He was sentenced to two months’ imprisonment at Manchester Magistrates’ Court, Greater Manchester Police has confirmed.
However, Liam Powell, 28, avoided jail as he was given a 12-month community order which will be in place until August 2025.
