Kathryn Elizabeth Stone OBE (born 8 August 1963)[1] is the former independent Parliamentary Commissioner for Standards of the British House of Commons from January 2018 until December 2022.
[2][1] She spent 11 years as the chief executive of the national charity Voice UK, being awarded an OBE in 2007 for services to people with learning disabilities.
Her high profile cases included finding against the prime minister Boris Johnson over a free holiday he took in Mustique courtesy of a Tory donor.
[5] Despite the fact that the prime minister encouraged a three-line whip on an amendment to change the standards system, the public backlash caused a reversal of policy and the next day Paterson resigned.
[6] In August 2022, she found that both Labour leader Keir Starmer and Shadow Foreign Secretary David Lammy had inadvertently broken the MP's code of conduct.
