Tesco has signed husband-and-wife TV presenters Vernon Kay and Tess Daly as the faces of its clothing ranges. The agreement is set to run for a year and will begin early next month, when the first shots of the duo will feature in stores. The images were taken in South Africa, with the couple modelling the supermarket's spring 07 clothing collection. Clothing chief executive Terry Green described the deal as a 'major coup' for Tesco. 'Not only do they look great, they are also regular Tesco shoppers,' he said. The retailer decided to work with the pair after research showed they were one of the most well-known celebrity couples in the UK.
