At the 2010 general election Cable was again returned as MP for Twickenham. With the election resulting in a hung parliament, Cable was a key figure in coalition talks, particularly the unsuccessful negotiations with the Labour Party. The Liberal Democrats entered a coalition agreement with the Conservative Party on 11 May 2010, and Cable was appointed Secretary of State for Business, Innovation and Skills on 12 May. The Queen approved his appointment as a Privy Counsellor, and he formally joined the Privy Council on 13 May 2010.
