POLL OF THE DAY: Are our prisons fit for purpose? YOUR VERDICT

Britain's prison system faced serious questions on Saturday after it emerged that the Manchester Arena bomber's brother attacked three officers in an "appalling" rampage at HMP Frankland.

Hashem Abedi's "unprovoked attack" left staff with life-threatening injuries including burns, scalds and stab wounds.

He threw hot cooking oil over them, then produced home-made weapons and proceeded to stab the officers, the Prison Officers Association said.

The POA's national chair Mark Fairhurst said: "We must now review the freedoms we allow separation centre prisoners have.

"I am of the opinion that allowing access to cooking facilities and items that can threaten the lives of staff should be removed immediately."

Shadow Justice Secretary Robert Jenrick said following the news: "The appalling attack on prison officers by the Manchester Arena bomber is extremely concerning. My thoughts are with the officers involved.

"There are serious concerns about the prison leadership's ability to contain the threat from Islamist extremist inmates... This deeply serious security failure must be a turning point."
