On 14 June 2007, the 27th Government of Ireland was elected by Dáil Éireann following nomination by the Taoiseach, and then appointed by the President. The Fianna Fáil–Green Party–Progressive Democrats coalition was led by the Taoiseach Bertie Ahern.
On that day Ahern announced to the Dáil that he had re-appointed Tom Kitt, TD to the post of Minister for State at the Department of the Taoiseach with special responsibility as Government Chief Whip and Minister of State at the Department of Defence. Dick Roche, TD was appointed on the same date to the position of Minister of State at the Department of Foreign Affairs, with special responsibility for European Affairs. On 20 June 2007, the Taoiseach announced that the Government had appointed the other Ministers of State.
