Which paper would the ABC prefer?

News from the UK:

A Freedom of Information response obtained by The Commentator website has revealed that the BBC buys more copies of the Guardian than any other national newspaper. Nearly 60,000 copies of Rusbridger’s rag could be found in Beeb buildings between April 2010 and February 2011, over 10,000 more than the Daily Mail. That’s despite the Mail having a circulation approaching ten times that of the Guardian.

Any bets on what the preferred newspapers at the ABC would be? Somehow, I doubt The Daily Telegraph would top the purchasing list.
