PARIS -- French lawmakers are expected to reject a bill that would legalize same-sex marriage five months after the country's highest court ruled that laws banning it don't violate the constitution.

Ruling conservatives of French President Nicolas Sarkozy's UMP party are expected to reject the bill in Tuesday's vote.

Supporters say it is needed to bring France into line with countries like the Netherlands, Belgium and Spain, which have already legalized gay marriage.

A January poll published by Canal Plus TV found 58 percent of respondents in France believe gays should be able to marry, a double-digit percentage point increase from a similar poll five years ago. Some 35 percent believe they should not.
