Home Secretary Theresa May is to be questioned by MPs over why one of the world's most wanted Al Qaeda terror suspects - captured by US special forces this weekend - was given asylum in Britain.
According to reports Anas al-Libi, who was seized on Saturday in the Libyan capital Tripoli, arrived in Britain in the mid-1990s and lived in Manchester after being granted political asylum.
The 49-year-old was accused by the US of involvement in the 1998 American embassy bombings in east Africa which killed more than 220 people.
Chair of the Home Affairs select committee, Labour MP Keith Vaz said: "This case raises serious questions about the motives behind asylum and national security decisions in the UK."
Theresa May will face MPs on October 15.
