Tesco Model found to be an illigal immigrant

Fatou Cham, a checkout girl (checkout number 6, Tesco, east London) was picked by Tesco to model for a glossy advertising blitz however she was later exposed as being an illegal immigrant.

Ms. Cham came to the UK from Gambia in 1998 on a student visa (studying banking, economics and finance at London Metropolitan University) however stayed after it expired in 2001.

Ms. Cham was chosen to model for the Florence and Fred clothing range by Tesco from a pool of hundreds of hopefuls for an ad campaign used in women's magazines. The advert showed Ms Cham modelling in a blue dress with the words below the image saying "Designed by F&F. Priced by Tesco. "

Immigration officers questioned her at her home in East Ham, east London, on Monday. She was quoted to say that she was excited to be chosen for the Tesco campaign and had hoped it would bring her other opportunities. However everything went wrong.

How do you think this might affect Tesco's image?
