Langdon was placed on 12 months' gardening leave on Monday. Speculation about his and Lepere's future at Euro RSCG began when Jim Heekin, Jones' predecessor, left in August after he was overlooked in a Havas management reshuffle. Heekin had worked with Langdon and Lepere at McCann Erickson and brought them into the Euro RSCG network in 2004.
Jones, the chief executive of Euro RSCG New York, was installed at the top of the network soon after Vincent Bollore took over as the chairman of Havas in July.
Jones became one of five managing directors of Havas alongside Mercedes Erra, the chairman of Euro RSCG France, and Stephane Fouks, who oversees the group's corporate communications interests.
Langdon's exit came in the wake of the London agency's loss of the £35 million Argos account to Clemmow Hornby Inge. The agency also lost its place on the COI Communications roster. Other losses over the past 18 months included Christian Aid and the British Heart Foundation.
Langdon, however, did win new business such as News Group, Superdrug and the £60 million pan European LG Electronics accounts.
No replacement for Langdon has yet been lined up. Chris Pinnington, the UK chief executive of Euro RSCG Worldwide, will run the agency in the interim.
