Daily Mail says Vodafone "spied on its own board"

The Mail on Sunday says it has evidence that Vodafone spied on its board of directors in 2006 to see whether or not they were loyal to Chief Executive Arun Sarin - and adds that Mr Sarin "presided over one of the most squalid episodes in UK corporate history". It's suggested that the company used call data and text message logs to try and prove a conspiracy against Arun Sarin in 2006. The newspaper says Vodafone has responded with a statement saying it will not comment on any particular investigation but it has never knowingly or deliberately breached any laws as part of any investigation.
