THE boss of MI5 has reiterated an apology he issued to the families of the Manchester Arena terror attack as they pursue a legal claim over a failure to act on intelligence which may have pre-1 vented the bombing.

In March last year, the agency's director general Ken McCallum expressed 'deep regret' that intelligence was not gathered which may have stopped suicide bomber Salman Abedi in his tracks. He said he was 'profoundly sorry' that MI5 was unable to prevent the 2017 attack which killed 22 people and left hundreds more injured.

He spoke out after a public inquiry found the bombing might have been prevented if MI5 had acted on intelligence received in the months before the attack when two pieces of information about Abedi were assessed at the time by the security service to not relate to terrorism.
