Food producer RHM has revealed that John Nelson will take up the role of non-executive chairman when the company is listed on the London Stock Exchange (LSE). Doughty Hanson & Co, which acquired RHM in August 2000 for £1.2bn (US$1.8bn), is considering realising some or all of its investment in the company by way of an offering and listing of shares on the LSE later this year, subject to market conditions.
