Sir Paul McCartney's estranged wife Heather Mills flew back to the UK for a gruelling three-hour meeting with top divorce lawyer ANTHONY JULIUS yesterday (05SEP06) to discuss legal proceedings. The former model, who had spent two weeks on holiday in the US, has high hopes for an impressive settlement - as Julius, nicknamed Anthony 'Genius', managed to bag his former client the late DIANA, Princess Of Wales, a staggering GBP17 million ($30.6 million) when she divorced British royal Prince Charles in 1996. But MCCartney, who has hired Prince Charles' former lawyer FIONA SHACKLETON in turn, is keen to pay Mills off in a 'quickie' divorce. An insider says, "Shackleton and Julius each want the best deal for their clients. "It will take as long as it takes."
