Giuliani, who teased the electorate by refusing to rule out his own candidacy in the generalelection, went about his business at his Wednesday morning news briefing.
Mr Johnson, who has advocated a new airport in the Thames Estuary, warned that the Conservatives would suffer if they did not rule out the move before the next generalelection.
