The Labour Party intends to increase the pressure on the Prime Minister in Parliament this week over his continued support of embattled minister John Banks.
John Key insists the ACT Party leader is an honest man and says he will continue to defend him against accusations that he lied about donations made to his 2010 Auckland mayoralty campaign.
Labour leader David Shearer says as Prime Minister, John Key should be finding out if Mr Banks lied to him as files from a police investigation cast doubt over whether he has been truthful about donations.
Mr Key has repeatedly said he accepts Mr Banks's assurance that he knew nothing about the donations and did not break the law.
He says he will not go back and have a look at the police investigation into the matter, because it is not for him to do a forensic analysis of it.
However, David Shearer says Mr Key is being negligent in refusing to look at the report and Labour will be questioning him length.
