Early results show that Ireland will be the first country in the world to legalise same sex marriage by popular vote. Over 70% of the country voted yes yesterday in favour of the change to the constitution. The final results are expected later today but it's safe to say that the yes side has won!
Edit: I should mention that this is Republic Of Ireland. Northern Ireland rejected Same-Sex Marriage
6 Counties (States) in the North of Ireland is part of the UK. The rest is the Republic of Ireland.They have different laws and currencies, etc. The Republic of Ireland is what is talking about in this post.
