NSW Opposition leader Michael Daley has called for the police to investigate the state government over a report that a member of his staff used a special hotline reserved for MPs to transfer a personal speeding fine into his wife's name.

On Friday the Herald reported that his office called the hotline - set up to allow MPs and their staff to speak with the Office of State Revenue on behalf of constituents - after a car owned by Mr Daley was detected travelling over the speed limit.

According to Mr Daley’s office his wife Christina was driving the car at the time of the offence, and after the hotline was contacted Mr Daley signed a statutory declaration transferring the fine which was then paid.

A spokesman for Mr Daley said it was common practice for MPs and their offices to call the hotline to place a “hold” on the processing of fines while constituents sought to contest them or provide further information. He said there was no suggestion that Mr Daley or anyone in his office had sought to avoid paying the fine or having points deducted from any licence.
