Mark Cadman named as JWT managing director.(JWT London)

The high-profile casualty of the Lowe saga returns to help fight for Sainsbury's.

Mark Cadman is joining JWT as its managing director, ending the speculation surrounding his future since he was denied the chance to take charge of Lowe London.

The agency named Garry Lace as its chief executive at the beginning of the year, a role Cadman is thought to previously have been offered in writing. Cadman is understood to have received compensation from Lowe.

His appointment will be seen as a move by JWT to enhance its chances of capturing the pounds 47 million Sainsbury's account, currently held by Abbott Mead Vickers BBDO.

Cadman was the senior suit on the rival Tesco account at Lowe, where he was the managing director. He and Russ Lidstone, the ex-Lowe planning chief signed by JWT in January, were among the key individuals who kept Tesco locked in despite Lowe's recent upheavals.

JWT is also challenging Lowe strongly on Nestle, having recently captured the foods giant's Quality Street, Double Cream and Milkybar brand assignments.

The two networks are also battling it out for Persil's global account.
