The Council of Ministers – under the presidency of the Prime Minister (or the President of Portugal at the latter's request) and the Ministers (may also include one or more Deputy Prime Ministers) – acts as the cabinet. Each government is required to define the broad outline of its policies in a programme, and present it to the Assembly for a mandatory period of debate. The failure of the Assembly to reject the government programme by an absolute majority of deputies confirms the cabinet in office.
