Poland's national-conservative Prime Minister Beata Szydlo announced her support for a ban on abortions on Thursday, backing the grassroots movement Stop Abortion on Polish radio.
"I support the initiative," she said, referring to the anti-abortion movement that is gathering signatures for a change in Poland's abortion law.
Polish law currently allows for abortion in cases of rape, if the foetus is severely disabled or if the pregnancy endangers the mother's life.
Szydlo said she is aware that her opinions might not represent all lawmakers of her Law and Justice Party. She previously said she was in favour of a parliamentary debate on the abortion issue.
"Each one of us will follow their own conscience," she said. Lawmakers have not had to toe the party line in votes of this kind.
Polish bishops recently denounced the existing law as an unacceptable compromise. Both the bishops and anti-abortion activists reject the termination of a pregnancy under any circumstances.
