WARSAW (Reuters) -A Polish parliamentary commission will inform prosecutors that the former prime minister's role in an abortive plan to organise elections by postal vote during the COVID pandemic may constitute a crime, its deputy chairman said on Thursday. Donald Tusk's pro-European coalition government, in office since December, has made a priority of holding to account those it accuses of wrongdoing under the previous nationalist Law and Justice (PiS) administration. "This is a political action by the commission, which is trying to use the mechanism of an investigative commission to fight political competition," former Prime Minister Mateusz Morawiecki said in an emailed statement.
