Senators spent 11 hours debating a bill on IVF on Wednesday 6 July in what has proved one of the most divisive issues in current Polish politics. The bill was passed in the lower house of parliament in late June and regulates state funding for couples seeking the treatment, but has been flatly opposed by chief opposition party Law and Justice. During Wednesday's Senate session representatives of various parties called for amendments to the bill, while others said that as Roman Catholics the prospective law is wholly unacceptable. Law and Justice Senator Dorota Czudowska claimed that ‘we are opening the gates of hell with this act’. Several senators from the ruling Civic Platform/Polish People's Party coalition suggested an amendment that would only allow the treatment for married couples.
