Senior coalition frontbencher Joe Hockey has called for an end to the public commentary over the sexual harassment accusations made against Speaker Peter Slipper.

''Frankly when there is an allegation of sexual harassment it should be left to the courts without all of this speculation around it and any attempts to to intimidate the staffer around it,'' Mr Hockey told ABC TV today.

James Hunter Ashby, a staffer in Mr Slipper's office, has lodged documents in the federal court accusing the Speaker of sexual harassment.

Mr Slipper, who is also being investigated over his use of Cabcharges, has stood aside as Speaker.
