Poland swears in opposition-backed Andrzej Duda as president
In May, Duda won a surprise victory in the presidential ballot, defeating Bronislaw Komorowski, who was seeking reelection as the candidate of the ruling Civic Platform (PO) party.
Duda's election pledges included cutting the retirement age, raising the tax-free income threshold and paying child benefits.
In Poland, it is the prime minister who has the most powers, but the president wields clout as head of the armed forces, has a say in foreign policy and the power to propose and veto legislation.
