A cross-border survey commissioned by RTÉ and the BBC has found two-thirds of respondents were either fairly or very comfortable with a close member of their family marrying someone of the same sex.

The results are likely to encourage campaigners who want Northern Ireland's Assembly to legalise same-sex marriage.

Two days ago the Assembly voted on a proposal to legalise same-sex marriage.

The measure was blocked by the Democratic Unionist Party, which deployed a measure called a petition of concern to do so. 

This was after Assembly members had voted in favour of change by a one-vote margin, 53 votes to 52.

The RTÉ and BBC survey is likely to encourage same-sex marriage campaigners.

It found that 64% of respondents in Northern Ireland were either fairly comfortable or very comfortable with a close member of of their family marrying someone of the same sex.

South of the border the figure was 67%. 

A special programme on RTÉ One television at 10.35pm tonight - Ireland's Call - will reveal the findings on a wide range of questions put to over 2,000 people from each side of the border.

Presented by Miriam O'Callaghan, the issues examined will include the level of support for a united Ireland.
