The prime minister nominates the cabinet, traditionally drawn from members of the same political party or parties in the Storting, making up the government. The PM organises the executive government and exercises its power as vested by the Constitution. Norway has a state church, the Lutheran Church of Norway, which has in recent years gradually been granted more internal autonomy in day-to-day affairs, but which still has a special constitutional status. Formerly, the PM had to have more than half the members of cabinet be members of the Church of Norway, meaning at least ten out of the 19 ministries. This rule was however removed in 2012. The issue of separation of church and state in Norway has been increasingly controversial, as many people believe it is time to change this, to reflect the growing diversity in the population. A part of this is the evolution of the public school subject Christianity, a required subject since 1739. Even the state's loss in a battle at the European Court of Human Rights at Strasbourg in 2007 did not settle the matter. As of 1 January 2017, the Church of Norway is a separate legal entity, and no longer a branch of the civil service.
