Premier’s ‘cosy’ texts to Brooks 
revealed

In one message, the Prime Minister thanked Mrs Brooks for letting him ride one of her horses, joking it was “fast, unpredictable and hard to control but fun”.

In another the journalist, who faces trial in connection with the phone-hacking scandal, praised Mr Cameron’s speech to Tory conference, saying: “I cried twice.”

The playful texts are apparently part of a cache of messages handed to Lord Justice Leveson’s media standards inquiry.

Very few have so far been made public – sparking accusations from Labour that they are being covered up.

The leak to the Mail on Sunday yesterday sheds further light on the close relationship between Mr Cameron and Mrs Brooks, who live near each other in Oxfordshire.

Her husband, racehorse trainer Charlie Brooks, was at Eton with the Prime Minister.

Both of the messages disclosed by the MoS were sent in October 2009, shortly after Mrs Brooks left her job as editor of the Sun and became chief executive of News International, which owns the paper.

In one, Mr Cameron wrote: “The horse CB (Charlie Brooks) put me on. Fast, unpredictable and hard to control but fun. DC.”

After his conference speech, Mrs Brooks texted: “Brilliant speech. I cried twice. Will love ‘working together.’”

Questions about Mr Cameron’s close links with Rupert Murdoch’s media empire, and Mrs Brooks in particular, came to the fore after the phone-hacking row erupted.

In her Leveson evidence, Mrs Brooks said at the height of the scandal in 2010 he sent a message through an intermediary urging her to “keep your head up” and expressed regret he could not be more loyal in public.

A Downing Street spokesman said: “The Prime Minister has always been happy to comply with whatever Lord Justice Leveson has asked of him.”
