British Prime Minister David Cameron sent an intimate text message to Rebekah Brooks thanking her for a "fast, unpredictable and hard to control but fun" ride on one of her family's horses.
The message, which could be read as suggestive, and another from Brooks to Cameron were disclosed to Lord Justice Leveson but were going to be kept secret, sparking claims of a cover-up by the inquiry and Downing Street.
They were revealed by the Mail on Sunday yesterday just weeks before Leveson is due to publish his report into the phone-hacking scandal which triggered Brooks' resignation from Rupert Murdoch's News International.
Chris Bryant, the Labour MP, has been pressing the Prime Minister in the Commons to reveal details of what he called "salacious" emails and texts between him and Brooks, whose husband, Charlie, is an old friend of the PM. Cameron has refused to respond to questions from Bryant, and No 10 has insisted that it has given the Leveson Inquiry all "relevant" documents.
