Further to the question asked by the Hon Member of 7 September 2016, Official Report, Column 321, I would add that my Rt Hon Friend, the Member for Derbyshire Dales, is a Minister of the Crown and a member of the Cabinet. He will attend a number of Cabinet Committees, which will be published in due course, and has duties directly related to the Duchy of Lancaster. The List of Ministerial Responsibilities will also be published in due course. He does not receive a Ministerial salary from public funds. Details of Private Office staff will be accounted for as part of the regular transparency data on gov.uk. The Government publishes on a quarterly basis details of Ministerial visits overseas. All Ministers have access to the Government Car Service for official travel.
My Rt Hon Friend also serves as the Party Chairman of the Conservative Party. Such arrangements are no different from the likes of Charles Clarke, Ian McCartney and Hazel Blears, all of whom held the posts of Minister Without Portfolio and Labour Party Chair under the last Labour Government.
I would also observe that under the Thatcher and Major Governments, senior figures such as Norman Tebbit, Kenneth Baker and Chris Patten served as both Chairman of the Conservative Party and Chancellor of the Duchy of Lancaster.
