Survivors of the London suicide bombings in July 2005 and relatives of the 52 people killed have renewed their calls for a public inquiry into whether the attacks could have been prevented.

It follows new evidence linking two of the bombers with five men sentenced yesterday at the Old Bailey for plotting a series of fertiliser bomb attacks in the UK in 2004.

A House of Commons committee is now to look at claims that M15 could have done more to prevent the attacks.
