There is no question that his departure has left National with quite a challenge. But it is probably the right time for both him and the party. Mr English is not going to achieve any more than he has and for the party it is better that it gets the inevitable blood-letting and infighting out of the way now, so it has ample time to prepare for the next election with a stable leader in place.
But for now, it is time for a big fight as candidates who believe it is their turn, put their hands up. So far, three have done so — Judith Collins, Simon Bridges and Amy Adams. Even if others do step forward, the leader is likely to come from that trio.
Of the three, Ms Collins seems to have the inside running. She probably won't ever be prime minister but she will be a perfect Opposition leader because she won't be afraid to go for the jugular. She will relentlessly attack Ms Ardern and hold her to account.
Time for someone with a bit of mongrel.
