Beleaguered National list MP Aaron Gilmore faces more heat with claims he tried to use his status to force a couple out of their rented home unfairly.
Otago University politics lecturer Dr Bryce Edwards says there is no doubt Mr Gilmore won't be on the list next year.
"There might be pressure over the next week or so for him to actually resign from parliament. Now of course John Key or anyone else in the National Party or parliament can't force him out."
Mr Edwards says there will be debate over whether he should remain as an MP or not stand for re-election next year.
"This has been a major embarrassment for his Party and it's not the first embarrassment, there's been a number of incidents in previous years, or when he was last a list MP, that has brought into question his reputation, his credibility."
