"Has anybody asked Mr Turnbull if he actually WANTS to be leader of the Coalition or be the Prime Minister?"
boatboy, given that Turnbull announced he was going to quit politics after losing the leadership by one vote then changed his mind I do think that he actually does want to lead and be PM.
The other indication is that Turnbull is worth some $180m so it's not as if he needs a job or the money, Turnbull would make a hell of lot more money in the private sector.
Turnbull mentioned on Q&A that he received thousands and thousands of letters from people suggesting he start his own party, I doubt few politician or people for that matter could make such a claim
