Paddy Power, the controversial bookmaker, is reviewing its creative advertising account after three years working with Crispin Porter & Bogusky. The review is being managed by Oystercatchers, which is contacting agencies about the brief and drawing a shortlist. Chemistry meetings will take place before Christmas. The client will then give the three or four selected pitching agencies a break over the festive holidays. The pitch is expected to finish in February 2015.
