About 40 prisoners have been moved out of Wandsworth prison after the escape of terror suspect Daniel Khalife.

Justice Secretary Alex Chalk told Sky News’ Sunday Morning with Trevor Phillips that inmates were moved “out of an abundance of caution”.

Khalife, 21, was arrested on Saturday after 75 hours on the run.

The breakout has raised questions about alleged understaffing and overcrowding at HMP Wandsworth, and why Khalife was being held at the less secure Category B facility when most terror suspects are held in HMP Belmarsh, a Category A prison.

Mr Chalk was not able to provide a figure when asked repeatedly how many terror suspects are in Category B prisons rather than Category A.

He said: “What I can say in respect of Wandsworth… I wanted to ensure out of an abundance of caution that every resource is put into that prison and security is preserved, some prisoners there on remand have been moved.”

He said the transfers happened this week, adding: “Additional resources have gone into Wandsworth, out of an abundance of caution around 40 prisoners have been moved.”

Pressed again on how many terror suspects are being held at Category B prisons, he admitted he has “concerns” which is why an investigation has been commissioned into the matter.

He added that the issue is “not without its complexities” and “people don’t automatically go into a category” based on the type of offence they are alleged to have committed.

On Thursday the government announced two reviews into Khalife’s escape, one which will focus on the “placement and categorisation” of all inmates at Wandsworth jail and another investigating all those people in custody currently charged with a terror offence.

Mr Chalk added that protocols at Wandsworth were in place but it is not clear if they were being followed, and that is something a review into the breakout will look into.
