MI5 had intelligence linking Manchester Arena attacker to bomb plot

Newsnight has been told the Security Service’s failure to prevent the Manchester Arena bomb attack in 2017 centred on a mistake so serious that it could be viewed as negligent.

Two sources told the BBC that MI5 received intelligence in the months before the 2017 attack, linking Salman Abedi to a bomb plot.

Earlier this month, the public inquiry into the attack concluded a significant opportunity to stop the attack was missed.

Newsnight’s Richard Watson has the story.
