By Sean Rayment, Security Correspondent, Sunday Telegraph Last Updated: 1:09am GMT 05/02/2007 Twice as many Islamist terror plots have been disrupted since the July 7 suicide bombings as has previously been made public, Britain's security services insist. Police raided properties in Birmingham after foiling an alleged plan to kidnap a British soldier A further six plots, which have been kept secret until now for security reasons, had been planned by groups across Britain since the London Underground and bus bombings in 2005.

Whitehall sources refused to provide precise details on security grounds.

The revelation demonstrates the scale of the task facing MI5 and the police, who are now discovering or disrupting some kind of terrorist plot in the United Kingdom every six weeks. Up to 12 plots of all kinds have been discovered in the past year and a half.

Dame Eliza Manningham-Buller, the director-general of MI5, revealed last November that there were an estimated 1,600 suspected terrorist involved in at least 200 networks in Britain.
