The National Party is in turmoil just 67 days before the general election after leader Todd Muller's shock resignation.
The party has been consumed by scandal over the leaking of Covid patients' private details a fortnight ago.
Muller's integrity came into question last week when he was repeatedly questioned about whether the party's health spokesman Michael Woodhouse had received any confidential information from former party president Michelle Boag and he replied that Woodhouse hadn't when he knew that he had.
A week of questions over Muller's handling of the leak scandal

• National's health spokesman Michael Woodhouse recognises the description of the information similar to info sent to him by party stalwart Michelle Boag in four emails between June 21 and 25.
• Woodhouse texts Boag to say he had not sent his info to the media. Boag says she knows because the info is different . The number of active cases Woodhouse was sent in June was lower than the 18 active cases Walker was sent but Boag does not tell him it was Walker.
