Lafarge (LAFP.PA) boss Bruno Lafont wants someone with experience of the cement industry to be chief executive in the French group’s planned tie-up with Swiss peer Holcim (HOLN.VX), daily newspaper Le Monde said. The choice of CEO for what would be the world’s largest cement maker is still unresolved after revised merger terms last month gave Lafont the role of non-executive co-chairman instead of chief executive as initially planned.
