It ends an 11-month search by the agency to replace Penny Buck, who left in January. The job has been held in an interim capacity by Sean Moore, the former Tequila\ creative director. Moore remains at the agency in a senior creative role.
Lines is expected to join DLKW Dialogue in the new year. He was the sole creative director at MRM for a year after Ed Pritchard, with whom he shared the role, left to join Meteorite.
At DLKW Dialogue, he will be responsible for a team of 22, working across DM, digital and sales promotion.
Lines' career spans 12 years at agencies including Brahm Leeds, IMP (now Arc), Claydon Heeley Jones Mason and Stretch the Horizon. In his final year at MRM the agency moved more towards a digital positioning and won a Cannes Direct Lion for a viral campaign for Microsoft.
Lines was promoted to joint creative director in 2003, having joined the agency a year earlier as its head of art.
