Donald Tusk’s name was chanted by supporters – some bearing EU flags – as he arrived for questioning in Poland over his handling of a plane crash that killed the former president.<br /><br />The president of the European Council was the country’s prime minister at the time of the disaster in 2010. <br /><br />Polish officials have been accused of negligence and several former ministers have been heard in the inquiry. The opposition have denounced the summons as politically-charged. <br /><br />A small number of Tusk’s critics also turned out at the national prosecutor’s office in Warsaw, some with posters depicting Tusk in prison uniform. <br /><br />Last year the state prosecutor’s office took over investigations – this inquiry is one of eight – into the crash seven years ago in Smolensk, western Russia, that killed 96 people including the then-President Lech Kaczynski. <br /><br />His brother, the leader of Poland’s ruling Law and Justice (PiS) party has accused Donald Tusk of “political responsibility”.<br /><br />In parliament recently Jaroslaw Kaczynski called opposition figures crooks who had “destroyed” and “assassinated” his twin.<br /><br />Tusk said the diatribe confirmed fears that Kaczynski wanted the justice system to answer to him.<br /><br />Poland’s rulers – facing demonstrations at home and at loggerheads with the EU action over a judicial overhaul – have long challenged an official report into the crash.<br /><br />But opponents say the probe into the previous government and Tusk himself is a political vendetta.<br />
