Polish Prime Minister and head of the ruling party PO Donald Tusk declared he would support PO's more liberal bill on in-vitro, the one prepared by PO MP Malgorzata Kidawa-Blonska, rather than the more conservative bill prepared by PO MP Janusz Gowin.

Tusk's stance, reinforced with his comments that politicians are responsible before people and not the Polish Catholic church (whose bishops have recently condemned in vitro method as "a younger sister of eugenics"), shows that the ruling party decided to make a step towards its liberal-inclining voters, who constitute the majority of the party's electorate, Warsaw University political scientist, Dr. Rafal Chwedoruk told Rzeczpospolita daily.
