Have you read any of news in NZ and why she said she was leaving. You probably shouldn’t just speculate, nor should I, but at least I’ve read what she said.Some say it was her potty mouth but there were probably other reasons possibly not wanting to work to get re-elected(probably not as popular as she had hoped going into an election)
She was never more impressive than she was when she addressed the community of the Christchurch mosque after (to our shame) an Australian murdered people at prayer.Having seen her on/thru BBC news..at different times..
She 'struck me' as being quite competent...
I was impressed.
