The UK government will publish the first wave of internal documents relating to the appointment of Lord Peter Mandelson as British ambassador to the US on Wednesday lunchtime.

The material will be accompanied by a statement in the Commons by the Chief Secretary to the Prime Minister, Darren Jones, at around 12:30 GMT, after Prime Minister’s Questions.

It is expected the documents will detail elements about the process prior to Mandelson taking up the role in Washington.

This will mark just the start of the release of information which would normally never be published but the government was forced to release by MPs.

Early last month the Conservatives used a parliamentary procedure known as a humble address to compel the government to release the papers.

Since then, a cross-party parliamentary committee, the Intelligence and Security Committee (ISC), has been involved in a complex process with government officials over which documents can be released – and with what redactions – to comply with the will of MPs without jeopardising national security or the UK’s overseas relationships.
