Thousands attended a pro-choice rally outside parliament in Warsaw on Sunday after the powerful leader of Poland's ruling party backed a call by Polish Catholic bishops for a full ban on pregnancy terminations.
Poland already has one of the most restrictive abortion laws in the European Union. Official statistics show only several hundred abortions are performed every year, but pro-choice campaigners say underground abortions are very common.
The debate around reproductive rights has been building up for months. The conservative Law and Justice (PiS) party, which came to power in October, plans to tighten regulations to bring them into line with the Catholic Church's teachings, infuriating liberals and women's rights activists.
