This week on Inside Parliament, 1 NEWS reporters Maiki Sherman and Mei Heron discuss the latest developments of the leaking of National leader Simon Bridges' travel expenses.
Ms Sherman said it had developed from a "whodunnit, to a who the heck dunnit", after an anonymous text message was sent to Mr Bridges and Speaker Trevor Mallard confessing.
National on Tuesday announced it would launch its own internal inquiry .
Mr Bridges told 1 NEWS the point of the inquiry was to determine if the leaker was from within National.
"It is possible the leaker is a National MP or a staffer, but the point is we don't know. It could be someone within Parliamentary Service or wider within Government."
Mr Bridges' MP expenses were released earlier than scheduled, with $113,973 spent on travel and accommodation between April and June.
