The Federal Coalition could come undone after the weekend's election results, but leader Brendan Nelson says there's no cause for alarm.
The federal National Party is considering a split from the Liberals, after a testing time in the weekend's elections.
The North Coast NSW seat of Lyne, the former seat of Mark Vaile, has been lost to new Independent MP Rob Oakshott, after decades of National Party rule.
The Coalition also received a scare in Alexander Downer’s previously safe South Australian seat of Mayo, where the Greens came within a stone’s throw of victory against Liberal candidate Jamie Briggs.
But, good polling in the WA elections has federal Nationals leader Warren Truss feeling good about the party's chances to fly solo.
The speculation has put renewed pressure on the Coalition leadership of Brendan Nelson, but this morning he's told 2GB’s Jason Morrison he's not concerned.
“I don’t think people should read too much into these things,” he said.
Dr Nelson says the absence of a Labor candidate in Mayo skewed the results.
“When Peter McGauran retired the Labor Party did run a candidate, by the way, and we had a six per cent swing against Mr Rudd.”
He also insists that ongoing speculation about former Treasurer Peter Costello taking over the leadership are unfounded.
"I can assure you that in two years' time... I'll be in this position."
