MSL Group parent Publicis Groupe has reported first quarter revenues of €1.6bn (£1.3bn), up 3.3 per cent on an organic growth basis.
Maurice Levy, chief executive of the French marketing services group, said the company "is now back to more satisfactory growth" after its poor fourth quarter of 2013.
He added that the merger with Omnicom "is moving forward even though progress is slower than anticipated".
