Question to the Cabinet Office:

To ask Her Majesty's Government which minister of full Cabinet rank holds ministerial responsibility for the UK constitution.

I refer the noble peer to the List of Ministerial Responsibilities, which can be found at:

https://www.gov.uk/government/publications/government-ministers-and-responsibilities

As stated in that document, the Paymaster General and Minister for the Cabinet Office has day to day oversight of constitutional affairs and efforts to maintain the integrity of the Union.
