Labour leader Andrew Little says Judith Collins' sponsorship deal with an Auckland car dealership cheapens her as an MP.
"I think it's completely out of order," Mr Little told reporters this morning.
A South Auckland dealership has given the former Justice Minister and National MP a car to use for six months and is covering her petrol costs. The deal is within the rules for an MP as long as Ms Collins declares it as a pecuniary interest.
Mr Little said her promotion of the dealership "cheapens the role of being an MP and it cheapens Judith Collins".
"No MP should be selling themselves as some sort of sponsorship product," he said.
The Labour leader said it did not matter that the car promotion was within the rules.
