New Zealand First MP Denis O'Rourke is under further pressure after being caught out over a fake testimonial on the Trade Me page of his classic car rental business.
Parliament's Speaker David Carter yesterday confirmed he is formally investigating the relationship between the list MP and his taxpayer-funded staffer Stephen James with whom he shares his Christchurch home.
However, the complaint from Queenstown resident David Simpson which sparked the investigation said there was "a clear case of Mr O'Rourke and Mr James conspiring to create bogus testimonials about a wedding car hire firm they both have an interest in".
The pair were directors of Christchurch-based wedding business Garden City Weddings.
After the business ceased trading, Mr O'Rourke continued to lease classic cars for weddings, including a 1948 Jaguar Mark V named Winston.
