The bitter struggle to unseat Warsaw's hard-right government foreshadows the wider struggle throughout the EU

Poland has often been the victim of violent external aggression over the years - of Prussian militarism, Nazi invasion and Russian domination. But as an extraordinarily vicious, polarising election battle nears its climax, the national story has taken a disturbing turn. Divided Poles are making victims of each other.

Fighting the neighbours, often alone, is a familiar Polish occupation, going back to the days of the Austro-Hungarian empire and before. After finally breaking free of Soviet communism in 1989, Poland joined the Nato alliance in 1999 and the EU in 2004. But new friendships did not dispel old habits and enmities.
