Bendel's move is the climax of his close association with the Wal-Mart-owned chain's account, on which he has been the senior suit for many years.
His remit will include advertising, PR, in-store and new product development and merchandising, as well developing a high-street presence for Asda to match Tesco.
Although UK-based, he is also expected to be involved in Wal-Mart's repositioning across international markets.
Bendel, 48, who joined Publicis when it acquired the then Geers Gross in 1991, said his decision was influenced partly by his current punishing travel schedule -- "I've had one weekend at home in the past four years" -- and partly because of the opportunity "to work for a company I love".
Seven years after its £6.7bn takeover by Wal-Mart, Asda has struggled to hold its own against Tesco, which now commands almost a third of the market compared with Asda's 16.5%.
