Olympics security firm G4S set to axe advisers after failing to buy ISS The finger of blame has also been pointed at Alf Duch-Pedersen. The 65-year-old chairman was put under pressure to quit by his own board earlier this month for pursuing the huge deal in such a volatile market. Further criticism was levelled at G4S chief executive Nick Buckles in October for his poor efforts when conducting pre-marketing meetings with the 12 key shareholders. All three financial and corporate advisers are expected to fight for their position in this week's beauty parade. A source close to Greenhill defended all of the advisers, saying: "The pre-marketing followed standard procedure and sub-underwriters were found." Bank of America Merrill Lynch; JP Morgan; Jefferies; and Citibank will be pitching for the potentially lucrative advisory roles. If axed, the stockbroker Hoare Govett will be left with just seven FTSE 100 clients on its books, and an uncertain future. Its owner, Royal Bank of Scotland, is looking to offload the firm as part of a cull at its investment banking arm. Deutsche claims to have picked up more clients over the past year than any of its competitors, in a string of City beauty parades.
