Brendan Horan has been booted out of New Zealand First’s caucus over the scandal involving his late mother’s estate. Legally, he can now remain on in Parliament as an independent MP, or join another party. But he ought not. He has no claim to represent anyone but those who party voted NZF, and if he can’t represent them, he must let the next person on the list do so. For him to hang around for 2 years on a taxpayer salary is untenable.
Plus, he wouldn’t want to force Peters to release the personal stuff.
[Update: looks like the personal stuff is starting to come out - Horan's use of his work phone to place TAB bets, lots of them in rapid succession]
