Mr Ardern had no idea what was in the policy, [National sources] said. It was known only to leader John Key and his deputy Bill English.
I guess it's either:
1. If your only principle is Gain Power, there's no need for your MPs to have any idea what their party's policies are;
2. Nat MPs are so incompetent they can't be entrusted with the dangerous knowledge of exactly why their party has put their bum on a seat in Parliament;
or both. Me, I'm picking it's actually both.
