Parliamentary Commissioner for Standards

The Parliamentary Commissioner for Standards is an officer of the British House of Commons.


The Commissioner is in charge of regulating MPs' conduct and propriety[1]. One of the Commissioner's main tasks is overseeing the Register of Members' Financial Interests, which is intended to ensure disclosure of financial interests that may be of relevance to MPs' work.[2]

He or she is appointed by a Resolution of the House of Commons, and works a four-day week. The Parliamentary Commissioner for Standards is appointed by a Resolution of the House of Commons for a fixed term of 5 years and is an independent officer of the House.[3] The remit of the Parliamentary Commissioner for Standards does not extend to the House of Lords: the post of Lords Commissioner for Standards was created in 2010.[4]

The current Commissioner is Kathryn Stone OBE.


The post was established in 1995 with Sir Gordon Downey as the first Commissioner, serving the newly formed Committee for Standards and Privileges. He investigated the Cash-for-questions affair.

The second Commissioner was Elizabeth Filkin (1999–2002), whose first case involved Peter Mandelson and a large loan which he had failed to declare in the Register of Members' Interests.[5] Her departure was controversial, with some people, notably Peter Oborne, claiming that high-profile MPs had effectively forced her out because they did not like her investigating them, although her job required it.[6]

The next Commissioner was Sir Philip Mawer. MPs he investigated include George Galloway and Derek Conway. He avoided investigating high-level MPs such as cabinet ministers. Unlike his predecessor he was appointed to a second term, but he did not complete it; he took up a new post at the beginning of 2008 as an independent adviser on Ministerial Standards to the then Prime Minister Gordon Brown.[7]

John Lyon, CB, was Commissioner from 1 January 2008 to 31 December 2012. In an article about Lyon's questioning by the parliamentary enquiry into MPs' expenses, Private Eye described him as "feeble" and an "establishment stooge".[8]

Kathryn Hudson served as Commissioner from 1 January 2013 until 31 December 2017.[9][10]

The current Commissioner, Kathryn Stone OBE, began her tenure on 1 January 2018.[11]

The institution of authorities outside the Parliament has become the way in which those systems have tried to prevent judicial enforcement: both the English Commissioner and the French déontologue (for some years, starting in 2011, appointed by the Bureau de l'Assemblée nationale) refer to the internal bodies of the respective Parliaments, which are responsible for evaluating any sanctions": (in Italian) Giampiero Buonomo, Su due sentenze della sesta sezione penale della Cassazione in tema di corruzione e parlamentari, Diritto pubblico europeo rassegna online, aprile 2019, p. 14.
