Jerry Hall's former lover and a £1.4bn hedge fund 'plot' Mr Attias is one of the brightest stars of hedge funds, with a glittering record at Rubicon and in a previous career as a City bond trader. He was first thrust into the spotlight when he began dating model Jerry Hall in 2001 in what was described as an "intense fling" with former wife of Mick Jagger, who is 10 years his senior. The two met on a spiritual enlightenment course which centred on the teachings of Kabbalah, an offshoot of Judaism to which she was devoted at the time. Mr Attias has also dated Lucy Yeomans, editor of Harper's Bazaar, Tara Bernherd, an interior designer and Virginia North, 20 years his senior and the ex-wife of the late businessman Lord White of Hull, the co-founder of Hanson. Mr Attias, who owns several properties including a £5.3 million five-bedroom house in Little Venice, west London, is said to have drawn up advice on how to date several women simultaneously called Tim's Rules, which included never sitting in the window of a restaurant and always calling her "darling" to avoid mix-ups over names. Now he is being sued accused by his former employer over claims that he and another senior manager, Santiago Alarco, attempted to stage a take-over of the firm while its chairman and co-founder Paul Brewer recovered from an accident. Mr Brewer, 55, was off work for 18 months and his wife Penelope, with whom he has three children, told he might not survive after the riding accident in summer 2009. At the time the fund - founded by Mr Brewer and Joseph Leitch in 1999 - was riding high, through successful investments at the same time as much of the industry was suffering in the economic downturn. Mr Brewer was estimated to be personally worth £40 million as a result of the success of his company, and particularly the part of the fund he managed. In his absence Mr Attias and Mr Alarco were temporarily promoted to chief investment officers, but after a few months started to "view the business and its clients as their own," Rubicon claims. Rubicon allege Mr Attias and Mr Alarco were not interested in Mr Brewer's recovery and were "only interested in finding out the consequences for their own compensation." Court documents [legal must keep] allege that when Mr Brewer eventually returned to work, Mr Attias effectively presented him with an ultimatum, threatening to leave if he and Mr Alarco were not given control of the fund. The two managers offered to buy the business, but when their bid was declined on the grounds that they "could not be trusted," relations deteriorated further, it is claimed. Mr Attias is accused of telling investors that the situation within the company had become "unsustainable," which lawyers say caused a major client to withdraw £69 million - a third of its total investment. Mr Attias is then said to have had talks with Mr Alarco and Catherine Cripps, a former funds manager at GAM Holdings, Rubicon's biggest investor, about setting up a rival fund together. Mr Brewer is said to have searched Mr Attias's company email account for evidence of the alleged "conspiracy." In January 2011, four months after Mr Brewer's return, Mr Attias decided to resign. Around the same time, GAM took out £187 million more of its investment, which Rubicon says was as a result of the secret discussions. A few months later, Mr Alarco also resigned, by which time GAM had withdrawn its entire investment of £345 million. Lawyers for Rubicon say that the staggered resignations "were intended to conceal the fact they were linked." They accuse Mr Attias, a keen polo player, of "enticing away" Mr Alarco to set up a new fund called SATA Partners with him and Ms Cripps and say the company's name is made up Mr Alarco and Mr Attias's initials. Mr Alarco says he was "unhappy" when he discovered the name Mr Attias had chosen as he had not committed to join SATA at that stage. Rubicon is trying to claim back the total of £17 million in bonuses they paid the two before their departure. Mr Attias, Mr Alarco and Ms Cripps deny there was a conspiracy to set up SATA, which has not yet begun trading, and say they quit because they had poor relations with their employers. A spokesman for Mr Attias and Mr Alarco said: "Tim Attias and Santiago Alarco refute the allegations made by Paul Brewer and Rubicon and have every confidence that the courts will find in their favour. They are astonished at these allegations which they believe to be maliciously motivated and which they believe are widely regarded in the market place as vindictive. Jack Irvine, Rubicon's public relations adviser, declined to comment.
