Before the 2010 general election, Mundell served as the Conservative Shadow Scottish Secretary. Following that election, the Conservative Party formed a coalition government with the Liberal Democrats. He held the non-cabinet role of Parliamentary Under-Secretary of State for Scotland, since the office of Secretary of State for Scotland was given to Liberal Democrat MP Danny Alexander (then Michael Moore and Alistair Carmichael), in view of the Liberal Democrats' greater representation of Scottish seats. On 9 June 2010, Mundell was appointed a Privy Counsellor.
