Agency: Leo Burnett London
Mahoney will oversee the agency’s 36 creatives, working with brands such as Marks & Spencer, Virgin Atlantic and Vodafone.
Mahoney led the creative output at Havas Worldwide London during its most-awarded period in two decades since joining in 2009. He has also been a creative director at Bartle Bogle Hegarty.
Ben Kay, the chief executive of RKCR/Y&R, said: "Mick gave the creative department at Havas a spirited unity and purpose. His creative ambition and track record of helping to build some of the UK’s best-loved brands fit perfectly with our own ambitions for the agency."
Mark Roalfe, the chairman and founder, said: "I’ve long been a fan of Mick’s. He will fit in well here culturally."
