Poles vote for a president on Sunday in the final round of the presidential election race between the incumbent President Bronislaw Komorowski and nationalist candidate Andrzej Duda.
The 62-year-old, who took office in 2010 after the death of his predecessor Lech Kaczynski in a plane crash, is expected to win re-election.
However, Komorowski finds himself neck and neck with his rival Duda, a 43-year-old lawyer and member of the European Parliament.
In the first round on 10 May, neither Conservative challenger Duda nor incumbent Komorowski gained the 50 percent needed to win outright.
Victory for Duda would mark the first major electoral win in almost a decade for the opposition Law and Justice party and boost the chances for his party at parliamentary elections in October.
Eight years in power, the centre-right Civic Platform has presided over rapid economic growth and rising salaries in eastern Europe's biggest economy.
But despite unprecedented prosperity, many Poles feel the fruits of their labour have been unfairly spread, resulting in increased inequality, and are eager for new faces at the top.
In Poland, it is the Prime Minister who leads the government.
The role of the President is largely ceremonial although the office-holder is head of the Polish armed forces and can veto legislation.
