The head of state is the president who is elected by the electoral college for a five-year term. Arif Alvi is currently the president of Pakistan (2018-). The president was a significant authority until the 18th amendment, passed in 2010, stripped the presidency of its major powers. Since then, Pakistan has been shifted from a Semi-presidential system to a purely parliamentary government. Since the amendment, the president's powers include the grant to pardon, and the ability to suspend or moderate any sentence passed by any court or authority.
