Two MPs are facing electoral commission investigation after electoral paperwork blunders. 

The Greens have referred suspended MP Darleen Tana to the Electoral Commission for failing to put a promoter statement on a magazine article about herself. 

At the same time, National MP David MacLeod has lost his Select Committee positions after he failed to declare almost $200 thousand in donations. 

Constitutional law expert Graeme Edgeler told Mike Hosking that the commission —and most likely the Police— will be investigating MacLeod. 

Edgeler says the New Plymouth MP could be liable under the illegal practice charge for not taking enough care.
