A bill which seeks to allow gay and lesbian couples to marry and adopt children has advanced in Luxembourg.

According to the Luxemburger Wort, the marriage bill, first introduced in 2012, cleared the Luxembourg parliament's legal affairs committee on Wednesday.

A vote in parliament is expected to take place sometime in June, or as the paper put it “after the Pentecost holidays and before the summer.”

The bill received wide support in the legal affairs committee. Representatives from the conservative ADR Party stood alone in their opposition.

Gay couples are currently allowed to marry in 8 European Union (EU) countries, including the Netherlands, Belgium, Spain, Sweden, Portugal, Denmark, France and the UK.

Luxembourg's openly gay prime minister, Xavier Bettel, the leader of the Democratic Party, has previously said he expects the nation will have marriage equality in 2014.
