French presidential candidate Marine Le Pen has pledged to end same-sex marriage, despite gaining support from the country's gay voters.

The far-right leader said she would abolish same-sex marriage in a long list of 144 pledges released this week.

President Francois Hollande signed a law that legalised gay marriage in 2013.

Le Pen, who is currently leading the polls for the spring elections, said the reversal of the same-sex marriage law would not be retroactive.

The National Front leader is proposing to revert back to the system in place prior to 2013.

This would mean gay couples are only able to enter into civil partnerships (PACS), according to legal experts at Marilyn Stowe.

Despite the pledge to abolish the same-sex marriage law - which was buried at number 87 on the list - the far-right leader has gained the support of LGBT voters in France.

Her support from gay married couples rose from from 19 percent in 2012 to 32 percent in 2015, the Guardian reported.

It has been suggested that one of the reasons behind the growing support among gay voters is the party's presentation of Islam as a threat to LGBT rights.

The party also has several gay men in senior positions, including Le Pen's deputy Florian Philippot.

However, the majority of voters are against a reversal of the same-sex marriage law, with an Ifop poll in August suggesting 65 per cent would be against a repeal.

Daily opinion polls show Le Pen winning the first round of the vote on April 23, with independent candidate Emmanuel Macron just ahead of Republican candidate Francois Fillon Fillon in second place.

However, polls suggest that either of the two men would beat Le Pen in a second-round vote on May 7.
