Sarah Wollaston

A former GP, Wollaston chaired the Health Committee from 2014 and then the Liaison Committee of all select committee chairs. The Health Committee's reports on social care funding, childhood obesity, the sugar tax and the effects of austerity on the NHS were notably cross-party and evidence-led, and she helped build the case for the soft drinks levy introduced in 2018. She left the Conservatives in 2019, which ended her time as chair when she lost her seat as a Liberal Democrat.
