The Finance Minister's accusing Labour of scraping the barrel with its questions in Parliament

The Opposition's grilled Nicola Willis on food price inflation at Question Time today.

Finance Spokesperson Barbara Edmonds asked her if the Prime Minister could still afford his grocery shop, which last year he famously said was about 60 dollars a week.

Willis wasn't amused.

She says Edmonds has been asking nasty and personal questions - and she won't sink to that level.
