 In the 2009 general election, after a campaign that was more than ever disproportionally focused on the Western Cape province, DA increased its national share of the vote to 16,7%, winning 67 seats in the National Assembly.Much of this increase came from the Western Cape, where DA won an outright majority on the provincial ballot thanks to a large increase of coloured support at the expense of several of the established parties.Zille was later sworn in as the provincial premier.
