MP Matt Hancock has been appointed minister for efficiency and reform at the Cabinet Office (CO).
Prime minister David Cameron yesterday announced Hancock would become minister for Cabinet Office and paymaster general, as part of the new cabinet formed after the Conservative Party victory in the general election.
His responsibilities will include civil services issues, government transparency, civil contingencies and cyber security.
Hancock takes over the brief from Francis Maude, who stood down as an MP at the election.
Hancock was elected to Parliament in 2010 representing West Suffolk, before joining the Public Accounts Committee. In 2013 he was promoted to minister of state for skills and enterprise.
Meanwhile, Oliver Letwin, chancellor of the duchy of Lancaster, has been promoted by Cameron to take overall charge of the CO.
