“A high‑profile Conservative with a strong loyalty record and a history of senior government roles.”
Sir Oliver Dowden is a Conservative MP for Hertsmere, first elected in 2015. He has held a string of senior government roles, including Deputy Prime Minister and Cabinet Office duties, and has also served as Chancellor of the Duchy of Lancaster. He has a long parliamentary career with a strong record of party loyalty.
