Channel 4 News has learned that police are advising four MPs whose names were found on a suspected terrorist hit list. The news follows the knife attack on Labour MP Stephen Timms. Political correspondent Cathy Newman reports.
Former minister Jim Fitzpatrick, the Labour MP for Poplar and Limehouse, is among the four MPs who have been offered advice and assistance by the police.
Channel 4 News understands Scotland Yard is reviewing security for all 650 members of parliament in the wake of fears over Islamist extremists.
Senior police sources have expressed concern that politicians may be at risk from so-called "self-radicalisers" - lone extremists who are not part of an organised plot but who are inspired by al-Qaida. Scotland Yard tonight declined to comment.
The disclosure comes two weeks after the former minister Stephen Timms was stabbed while speaking to constituents. The attack in east London by a young Asian woman is now being treated as a terrorist investigation. His assailant is believed to have been radicalised by Islamist extremists.
