London, Aug 9 (IANS): London Mayor Boris Johnson has said that at the moment he does not want to challenge David Cameron for the post of prime minister.

"At the moment, I certainly don't want to be prime minister," the mayor said.
Johnson joked about how he got stuck on a zip wire at an event for the London Olympics.
"How on earth could you elect that guy? How could anybody elect a prat who gets stuck on a zip wire," he said.
