Geremek was a historian by training
Bronislaw Geremek, a key anti-communist dissident and former Polish foreign minister, has been killed in a car crash, police have announced.
Mr Geremek, 76, died when the car he was in hit an oncoming vehicle in western Poland on Sunday afternoon.
He was one of the key advisers to Lech Walesa, the Solidarity union leader which helped topple communist rule.
Mr Geremek was foreign minister from 1997-2000 and European Parliament member since 2004.
Mr Geremek died when his Mercedes car collided with a van near the western town of Lubien, police spokeswoman Hanna Wachowiak said.
It was not immediately clear on whether he was driving at the time.
The former foreign minister - a historian by training - oversaw his country's accession to Nato.
