Woolwich murder: Lee Rigby's death was not preventable

The murder of Fusilier Lee Rigby could not have been prevented despite his killers appearing in seven intelligence investigations, a report has found.

Although the parliamentary inquiry found errors in the operations, chairman Sir Malcolm Rifkind said they were not "significant enough to have made a difference".

The soldier was killed near Woolwich Barracks in London on 22 May 2013.

Michael Adebolajo was sentenced in February to a whole-life term and Michael Adebowale was jailed for a minimum of 45 years for the killing.
