Andrew Moore joins the retailer as its new chief commercial officer, the latest of a string of senior appointments made this year.
He is credited with developing Asda’s fashion brand George into a global presence, and leading the retailers wider general merchandising team.
Prior to his role at Asda, Andrew held senior positions at Marks & Spencer and Woolworths in South Africa.
Earlier this year Wilko, which reported a pre-tax operating loss of £65m in the 12 months to 3rd February, poached Specsavers retail director Craig McGregor to take on the same role.
The news came shortly after Asda’s former financial chief Alex Russo joined Wilko as its new chief financial officer and executive board director.
