This afternoon, in a brief speech from the main stage of the Get It On Big Gay Out, Key upped the ante, confirming his intention to vote for the bill in its next two readings, and expressing his belief that many other MPs will follow his lead. “As PM I think if I vote for it a whole lot of MPs will vote for it too,” he said, to a warm reception from the crowd.
