Home secretary Jack Straw made it an 'urgent priority' to locate the unexploded wapons left behind by Luftwaffe raids in world war two. Boffins spent two years pouring over data from local authorities, emergency services and the military. But now they have given up on the task because no one knows after all this time where the bombs actually fell.
Some local authorities have destroyed or lost records of local raids despite being responsible for tracking unexploded bombs during the war. Others have conflicting data. A home office spokesman said: 'It would be worse to have a wrong register than no register'.
