Slovenians have overturned a law allowing same-sex marriages, in a triumph for the conservative opposition over the leftist governing bloc.

With nearly all the ballots counted in a referendum, 63.4 per cent voted against an amendment defining marriage as a union of two people, as opposed to the union of a man and woman.

The result exceeded the required support of 20 per cent of the 1.7 million registered voters comfortably, by some 40,000 ballots.

Turnout was 36 per cent.

Slovenia had introduced the amendment allowing gay couples to marry in March.

Opponents, rallying around the slogan `Children are at Stake', and supported by the dominant Catholic Church, petitioned for the referendum.
