The prime minister would serve as the deputy to the president if both are from the same political party. On certain occasions, when the president is not from the majority party in parliament or a national government is formed, the prime minister would be appointed from a party different from the president's. In such a situation, the prime minister would serve as the ''de facto'' head of government.
In 2015, the
nineteenth amendment restored a certain degree of powers to the premiership.
