Prime Minister Julia Gillard's grip on parliament has slipped even more, with news Nationals federal MP Tony Crook will formally be part of the Federal Nationals' party room in Canberra.
The leader of the Nationals, Warren Truss, says the decision by the member for O'Connor will ensure he can contribute to outcomes that benefit his constituency and the party.
Mr Crook says in a hung Parliament, he had believed regional Western Australia would be best served by his sitting on the cross-bench.
But he says parliament has changed, and the recent changes to the make-up of Parliament have tarnished the reputation of the cross-bench.
Since entering parliament, Mr Crook has voted mostly with the coalition and backed Labor in only 12 per cent of ballots.
