Mr Al Sarraj’s self-imposed isolation was soon punctuated by an unwelcome fame among prisoners.

“People would come up to me and say : ‘Are you Kadhum? I have heard about you. You are from London.’

But his new-found status in the camp was to cause him great pain.

“They would say ‘please, you are the only one that speaks and writes in English’.

“I helped them, but sometimes I used to hate it.

“I just wanted to be alone and rest so I can concentrate on my family and my work.

“It was better than having any contact and having to deal with everyone else’s problems.”
