Soldiers are being deployed on Britain’s streets to support armed officers after the terror threat level was raised to its highest level following the Manchester Arena suicide attack. The military will guard key sites including Buckingham Palace, Downing Street, embassies and the Palace of Westminster.

It comes as the threat level was raised from severe to critical, meaning an attack may be imminent, after 22 people were killed and 119 injured in the bombing at the end of an Ariana Grande concert. Ten victims have been identified so far, including a Polish couple and two mums collecting their daughters from the concert, and fans as young as eight.

Home Secretary Amber Rudd told BBC Breakfast that up to 3,800 troops can be deployed as part of Operation Temperer.  The bomber has been named as 22-year-old Salman Abedi, as security services probe his links to a known ISIS recruiter and whether he was part of a terror network.
