Former royal butler Paul Burrell has been given a public apology and substantial damages from the publisher of the Daily Mirror newspaper over phone hacking and “repeated invasion of his privacy”.Mr Burrell, a friend and confidante to Diana, Princess of Wales, brought legal action against Mirror Group Newspapers (MGN) after he was targeted by private investigators instructed by the publisher and had his voicemails intercepted.At the High Court in London on Tuesday, lawyers for Mr Burrell said MGN – which publishes the Daily Mirror, Sunday Mirror and The People – had agreed to pay substantial damages plus his legal costs, as well as accepting liability for the unlawful acts.Solicitor Francis Leonard, for Mr Burrell, said: “Between 1995 and 2008 the claimant was targeted by the defendant because he was a close friend and trusted confidante to Princess Diana and then subsequently because of his role within the public sphere following his departure from the royal household.
