When Christopher Luxon first survived a vote of confidence among National MPs in April, Act leader David Seymour said at the time he was pleased to see the party stable and "drawing a line under any trouble they may have had." Fast forward 4 months, and the Prime Minister's leadership is being tested again. He's survived another vote of confidence. Just like the last one, National's coalition partners, ACT and NZ First, were watching on. ACT leader and Deputy Prime Minister David Seymour spoke to Melissa Chan-Green.
