ROB OAKESHOTT is a veteran of political attacks from his arch rivals the Nationals, but the independent federal MP was clearly unprepared for being berated on Twitter by the wife of the Deputy Premier, Andrew Stoner.

Cathy Stoner lashed out at Mr Oakeshott a day after he voted with the government to prevent Parliament from removing the Speaker, Peter Slipper.

The motion, which failed by one vote, was put by the federal Opposition Leader, Tony Abbott, after offensive text messages by Mr Slipper about female genitalia were made public during a sexual harassment case being brought against him by a former staffer, James Ashby.

''You have abused the trust of all who supported you + your constituents,'' Mrs Stoner tweeted to Mr Oakeshott.
