To ask His Majesty's Government, further to the Written Answer by Baroness Neville-Rolfe on 21 September (HL9981), whether they will now answer the question put, namely, what has been the average tenure of office notwithstanding machinery of government changes, during the past 10 years, of (1) the Prime Minister, (2) the Chancellor of the Exchequer, and (3) the Secretary of State for (a) Foreign Affairs, (b) Home Affairs, (c) Education, (d) Health, (e) Defence, (f) Transport, (g) Culture, Media and Sport, (h) Environment, Food and Rural Affairs, (i) Work and Pensions, (j) Northern Ireland, (k) Scotland, and (l) Wales.

The Cabinet Office does not collate this data centrally. Notwithstanding, to assist the noble Lord’s scrutiny, a list has been compiled from public information. The 10 year period used is 4 October 2013 - 4 October 2023.

Where Ministers were in post on 4 October 2013, our calculations have used the start of their tenure, which may precede that date.
