A review of the Windrush generation scandal will have full access to Home Office information, Theresa May has promised ahead of a Labour move to force disclosure of internal documents.

The Prime Minister, who was home secretary before entering Number 10, promised a package of measures to bring transparency on the issue.

Labour hopes to use a parliamentary procedure to force ministers to hand over correspondence including text messages and emails – between ministers, officials and special advisers between May 2010 and 2018.

At Prime Minister’s Questions, Mrs May said Home Secretary Sajid Javid would set out the actions being taken by the Government on the issue.

She said speed is of the essence and Mr Javid will be commissioning a full review of lessons learned, independent oversight and external challenge with the intention of reporting back to this House before we rise for the summer.

The review will have full access to all relevant information in the Home Office, including policy papers and casework decisions.

Shadow home secretary Diane Abbott said the scandal had exposed something rotten at the heart of Government and full disclosure of the facts was required.

The Tories are expected to oppose Labour’s motion, which would see the internal documents handed to the Home Affairs Committee.
