Embarrassing WhatsApps, but no vetting report: what will be in the new release of Mandelson files?

Cabinet Office is expected to publish more than 1,000 pages related to former US ambassador’s appointment to role

• Mandelson files show no mitigation of security concerns over US appointment

On Monday the Cabinet Office is expected to publish the second tranche of the Mandelson files – more than 1,000 pages of documents relating to his appointment as UK ambassador to Washington.

The document dump will be the second-largest to the House of Commons after the Chilcot inquiry report into the Iraq war, and its disclosures threaten to again raise awkward questions over Keir Starmer’s judgment in giving Peter Mandelson the UK’s most important diplomatic job.
