A legal feud between the Barclay brothers' families has come to light after a court heard Sir Frederick had private conversations recorded by his twin brother\u2019s son in the Ritz hotel in London.\r\n\r\nFrederick, 85, and his daughter Amanda claimed Sir David's three sons were \u201cparties\u201d to the secret recording of their private conversations in the conservatory of the hotel, which the Barclays own.\r\n\r\nThe high court heard yesterday that the children of Sir David and Sir Frederick are in a serious disagreement about the family trust, and the quarrel has \u201cpitched cousin against cousin\u201d.\r\n\r\nFrederick, 85, and his daughter are bringing legal action in which they allege breach of confidence, breach of data protection laws, and misuse of private information, against four relatives: Alistair, Aidan, Howard, Aidan\u2019s son Andrew, and a fifth figure Philip Peters, who has a board position within the Barclay group of companies.\r\n\r\nThe \u2018bug\u2019 was only rumbled in January when Alistair was reportedly filmed handling the device in the conservatory. It is not yet clear how long before its discovery the bug had been live.\r\n\r\nIn an exercise of flare seemingly designed to help screenwriters draw inspiration, Desmond Browne QC, representing father and daughter, said: \u201cWe all remember Tolstoy saying \u2018each unhappy family is unhappy in its own way\u2019. Here, the children\u2026have been at odds\u2026concerning the family trusts, and cousin, sadly, has been pitched against cousin.'\r\n\r\nSpeaking to Mr Justice Warby, he went on: \u201cIt is alleged that the defendants have surreptitiously recorded the conversations of Sir Frederick and his daughter Amanda, both between themselves and with others, over a period of months.\u201d\r\n\r\nHe added: \u201cThe defendants knew the conversations were private and confidential, but they nevertheless recorded them, commissioned transcripts and then conducted discussions about them.\r\n\r\n\u201cThe matter came to light when the first defendant, initially the only defendant, Alistair Barclay, was filmed late on the night of January 13, handling the bug placed in the conservatory at the Ritz, which was known to be often used by Sir Frederick. I gather it was somewhere he could go to smoke a cigar.\u201d\r\n\r\nBrowne requested that the court assert a non-disclosure order which would prevent the defendants from disseminating the contents of the recordings.\r\n\r\nOn the other side, Heather Rogers QC, said her clients (which include all five defendants) would have been able to secure a lot of information even without the recordings, and that despite \u201cample opportunity\u201d, there was \u201cno evidence of dissemination\u201d.\r\n\r\nYesterday was the first time the previously private hearings were allowed by the judge to be made public.\r\n\r\nThe Barclays have interests in media, hotels and retail, including The Daily Telegraph, the Ritz and Shop Direct, in a business empire worth billions.
