Exclusive: Vince Cable, Chris Huhne and Norman Lamb claim they were targeted for stories or to 'exert political influence’

Two former Lib Dem cabinet ministers and a former party whip are suing the publisher of the Sun and the defunct News of the World, claiming that their phones were hacked for stories or to “exert political influence”, including when Rupert Murdoch was seeking approval for a takeover of BSkyB.

Journalists working at Murdoch’s newspapers are said to have unlawfully targeted the former business secretary Vince Cable as well as Chris Huhne, a former energy and climate change secretary, and Norman Lamb, a whip and sometime adviser to the then deputy prime minister, Nick Clegg.
