Australia ? Australia’s Prime Minister Kevin Rudd and his treasurer are rejecting opposition calls to resign over their relationship with a car dealer which commentators say has created the 19-month-old government’s biggest political crisis.

Opposition Leader Malcolm Turnbull said Saturday that Rudd and Treasurer Wayne Swan repeatedly misled Parliament this month when they denied that Rudd’s friend, car dealer John Grant, had been given special attention when he applied for a government loan to cope with the global credit crunch.

Turnbull said Rudd and Swan had no choice but to resign.

Swan said today he would not.

Rudd maintains that he did not mislead Parliament and said Saturday that Swan had “acted entirely appropriately.”
