Peter Oborne's excoriating column [2] on the Tories and the Murdochs in today's Telegraph includes the revelation that David Cameron texted former News International chief executive Rebekah Brooks at least 12 times a day. Oborne writes:

A fresh embarrassment concerns Rebekah Brooks, who providentially retained the text messages she received from the Prime Minister, which I’m told could exceed a dozen a day. These may now be published, a horrible thought.

If true, it evidences why David Cameron's upcoming appearance at the Leveson inquiry (he will likely appear in mid-June) could prove so embarrassing for the Prime Minister. Indeed, last week's Sunday Times [3] (£) reported that Brooks is "ready to disclose any text messages and emails between herself and David Cameron if required." (Cameron reportedly signed letters to her "Love, David".)

It's easy to see how the news  of Cameron's daily contact with the striking Brooks (Tweeters are already quipping about her being his "Monica Lewinsky [4]") could permanently reduce him in the eyes of the public.
