Police forces have already mobilised 4,000 trained public order officers to deal with the violence and disorder sweeping Britain.
But with the unrest showing no sign of abating, police leaders have boosted the numbers by an extra 2,200 officers. They will be on standby across the country and can be mobilised to support colleagues locally and regionally.
Meanwhile, Jordan Parlour, from Seacroft, Leeds, has become the first person to face prosecution for posting allegedly criminal messages linked to the riots, while the Northern Ireland Assembly will hold an emergency session after unrest in Belfast, heaping pressure on Sir Keir Starmer to recall parliament.
