David Cameron will become the first sitting UK Prime Minister to appear on The Late Show With David Letterman when he stops by for Wednesday’s show. In New York to give a keynote speech to the U.N. General Assembly, Cameron will use the slot to “bang the drum for British business” as he attempts to keep the country basking in the Olympics afterglow. The British press is having fun at the prospect with The Times calling it a “high-risk move” and The Guardian surmising it’s “brave, if slightly foolhardy” given Letterman’s ability to ask “awkward” questions. London Mayor Boris Johnson appeared on The Late Show in June and almost came up short when the host asked the famously disheveled politician how long he’d been cutting his own hair. A Downing Street aide told The Times that Cameron’s interview “will certainly have some light-hearted parts.” Perhaps not so light-hearted if Letterman queries the PM on his cozy relationship with some of the folks involved in the News Corp. phone-hacking scandal: Both his former communications director, Andy Coulson, and his neighbor, Rebekah Brooks, are set to appear in court Wednesday on charges related to the scandal.
