The president is a formal head of state with limited and specific powers, who appoints the prime minister, as well the other members of the cabinet on a proposal by the prime minister. From 1993 until 2012, the President of the Czech Republic was selected by a joint session of the parliament for a five-year term, with no more than two consecutive terms (2x Václav Havel, 2x Václav Klaus). Since 2013 the presidential election is direct. Some commentators have argued that, with the introduction of direct election of the President, the Czech Republic has moved away from the parliamentary system and towards a semi-presidential one. The Government's exercise of executive power derives from the Constitution. The members of the government are the Prime Minister, Deputy prime ministers and other ministers. The Government is responsible to the Chamber of Deputies. The Prime Minister is the head of government and wields powers such as the right to set the agenda for most foreign and domestic policy and choose government ministers.
