Former Polish Interior Minister Mariusz Kaminski said he had started a hunger strike as a "political prisoner" on Wednesday, a day after he was detained by police at the presidential palace and sent to jail on abuse of power charges. The events mark a gear change in new Prime Minister Donald Tusk’s efforts to undo policies of his predecessors, the nationalist Law and Justice (PiS) party, and punish those accused of wrongdoing during their time in power.
