The Conservative Research Department (CRD) is part of the central organisation of the Conservative Party in the United Kingdom. It operates alongside other departments of Conservative Campaign Headquarters in Westminster.
The CRD has been described as a training ground for leading Conservative politicians. Former CRD advisers to have served in the Cabinet include former Prime Minister David Cameron, incumbent Deputy Prime Minister Oliver Dowden, former Chancellor of the Exchequer George Osborne, former Chancellor of the Duchy of Lancaster Oliver Letwin and former Health Secretary Andrew Lansley. After 1945, Enoch Powell, Iain Macleod, Reginald Maudling and Chris Patten passed through it.[1]
