The father of a woman killed in London's 7/7 terrorist attacks has criticised MI5.
John Taylor, whose daughter Carrie died at Aldgate station, said security services should have sent better quality images of the attackers to their supergrass Mohammed Junaid Babar.
The former terrorist who became an informant was shown grainy photographs of Shezhad Tanweer and Mohammad Sidique Khan in 2004 but failed to recognise the men.
