New Zealand member of parliament Maurice Williamson addresses the house briefly on the subject of same-sex marriage, which passed by a larger-than expected margin of 77-44 on Wednesday. The woman shown several times is a principal sponsor of the bill, Louisa Wall, who shepherded its passage. (Note: Based on a news report I read, I previously misidentified her as another MP, Metiria Turei. My apology for the error.)
Immediately after the vote, members of the losing side quietly left the house, then when the result of the vote was formally announced, spectators in the gallery and some members of parliament joined together in singing a love song in the Maori language of the country's original population, "Pokarekare Ana."
