Sydney - Liberal Party lawmakers arrived Tuesday at Canberra's Parliament House for a leadership ballot that pits struggling incumbent Brendan Nelson against his treasury spokesman Malcolm Turnbull.
Nelson, 51, declared the position vacant in the hope that in a new vote he could improve on the 45-42 winning margin he achieved nine months ago.
Nelson, a former general practitioner, is woefully behind Prime Minister Kevin Rudd in the opinion polls. His party is further behind Rudd's Labor than it was when losing the general election in November under John Howard.
