Opposition frontbencher Tony Abbott has again moved to play down speculation over the Liberal leadership, saying no-one is better equipped to lead the party than Brendan Nelson.
The latest Newspoll, released today, shows Dr Nelson gained two points to 14 per cent as preferred prime minister in the past fortnight.
But he remains well behind Prime Minister Kevin Rudd who commands strong support at 65 per cent.
Mr Abbott has told ABC TV the latest poll result is discouraging, but says he doesn't believe anyone would do a better job of leading the party in the current circumstances.
Mr Abbott refused to back shadow Treasurer Malcolm Turnbull as a possible replacement for Dr Nelson.
He also refused to be drawn on whether former treasurer Peter Costello might make a bid for the Liberal leadership.
