Parliament returns from recess today with the Government braced for a major Westminster storm, as ministers prepare to publish the next tranche of files relating to Peter Mandelson’s time as ambassador.
Around a thousand pages of documents are expected to be released this afternoon, including WhatsApp messages and emails exchanged between Mandelson and ministers, officials and special advisers from across government. The publication, reportedly one of the largest ever laid in Parliament, will dwarf the 136 pages released in March and is expected to trigger significant political fallout.
The precise timing of the release remained unclear on Monday morning, but the files are expected to be published shortly before a Commons statement from Darren Jones, which will take place after 3.30pm. Parliamentary convention would usually see documents published at least 45 minutes to an hour before a statement, though the Government was criticised last time for giving MPs only half an hour to examine the material before ministers came to the House.
Those familiar with the contents have warned that the files will contain a series of embarrassing exchanges for senior figures in government, including private remarks made about Keir Starmer and messages in which Mandelson appears to have offered advice to Cabinet ministers on how to do their jobs. While expectations within government are that the documents may not be serious enough to force resignations, they are likely to expose private frustrations and deepen existing tensions within Labour.
The timing is particularly difficult for the Prime Minister, with the party already in flux and speculation continuing about the future direction of Labour. Allies of senior figures have been nervous for months that cosy exchanges with Mandelson could damage future prospects for promotion or even leadership bids. Those closest to the Blairite wing of the party are expected to be most exposed, while Cabinet figures less closely associated with Mandelson are likely to avoid the worst of the embarrassment.
The document drop will land on a busy day in Westminster. Wes Streeting is due to make a speech urging the Government not to abandon his NHS reforms, as the NHS Modernisation Bill goes through second reading in the Commons. The former Health Secretary will argue that ministers are making the same mistake that has held the NHS back for years by claiming that higher spending alone has reduced waiting lists.
Elsewhere, Andy Burnham continues to build momentum, unveiling a new northern soul-inspired brand with the slogan “Change Labour - keep the faith”, while polling reported by The Times suggests Labour is now facing serious competition from Reform among trade union members. Reform is reportedly ahead of Labour among Unite and GMB members, underlining the scale of the challenge facing the party as it attempts to steady itself.
Amid the Mandelson files, NHS tensions, leadership speculation and Reform’s growing strength among Labour’s traditional base, the return from recess looks set to be anything but quiet for Keir Starmer’s Government.
