Whanganui National MP Chester Borrows will face a trial over a charge of careless use of a motor vehicle causing injury.
His application to have the charge dismissed was turned down today by District Court judge Jim Large.
The charge relates to an alleged incident in March when Borrows and cabinet minister Paula Bennett who, had been speaking at a breakfast function, were driving away from the venue.
The meeting had attracted a group of protestors against the Trans Pacific Partnership.
Borrows, who is also Parliament's deputy Speaker, had pleaded not guilty.
He appeared in the Whanganui District Court last month when the judge, on his own motion, suppressed all evidence and argument in relation to the charge.
No trial date has yet been set down.
