Shadow Home Secretary Yvette Cooper told ITV News it was "astonishing" Theresa May did not know whether a terror suspect who escaped surveillance by wearing a burqa had his passport with him.
On-the-run terror suspect Mohammed Ahmed Mohamed, who is seeking damages from the Government over torture allegations, reportedly cut off his monitoring tag with a sharp object before fleeing.
Ms Cooper said: "The idea that the Home Secretary doesn't know even whether he has his passport or not is astonishing.
"It's another sign that the TPims regime Theresa May brought in - that weakened the controls - is simply not working."
