Next Sunday's Polish parliamentary election is, on current evidence, too close to call. This is somewhat unexpected – in contrast with the majority of its predecessors in the post-communist era, the coalition government of the liberal-conservative Civic Platform (Platforma Obywatelska, PO) and the Polish Peasant Party (Polskie Stronnictwo Ludowe, PSL) has enjoyed higher levels of public approval than disapproval, and for much of its tenure looked set to become the first government in post-communist Poland to win a second term.
