Aug. 3 (Bloomberg) -- The ex-wife of U.K. insurance multimillionaire John Charman won a record 48-million pound ($90 million) divorce award, cementing England's reputation as among the most lucrative places to divorce rich men. Charman, 53, the chief executive officer of insurer Axis Capital Holdings Ltd., was married for 29 years before splitting from his wife Beverley in 2005. He said he would appeal the decision, calling the size of the award ``grotesque and unfair.'' The settlement, issued at a private hearing last week at the High Court in London, tops the 30 million pounds awarded to the ex-wife of WPP Group Plc Martin Sorrell last year. It also comes about a week after ex-Beatle Paul McCartney, worth an estimated 825 million pounds, formally filed for a divorce from his wife of four years, ex-model Heather Mills.
