MPs raise doubts over missing Mandelson vetting documents

File detailing security mitigations is among those withheld at the request of the Metropolitan police

Ministers have faced renewed cross-party pressure in parliament over documents missing from a 1,500-page release of papers about Peter Mandelson’s appointment as ambassador to Washington.

Despite the volume of information published on Monday, crucial documents were withheld at the request of the Metropolitan police on the grounds that they could “potentially prejudice” an investigation. They include a document summarising the vetting process, which concluded with officials recommending Mandelson not be given security clearance.
