It's one of the more extraordinary pieces of speculation in an already extraordinary race for the White House.

Rumour has spread that Rupert Murdoch's most colourful editor Colin "Col" Allan could become a key media advisor to Donald Trump if the Republican presidential frontrunner gets the party's nomination to run for President of the United States.

Sources told Fairfax Media they were convinced the Australian-born Mr Allan, famous for visiting Scores strip club with Kevin Rudd, has been sounded out for an advisory role by the billionaire, who has regularly flown Mr Allan in his helicopter to play rounds of golf as part of their long-standing acquaintance.

Observers noted that such an unlikely pairing would give Mr Murdoch, who has softened his stance against Mr Trump on Twitter, a close confidante in the Trump camp.
