Mary Portas: Secret Shopper, Channel 4

She’s back: the retail guru and style icon, with her sharp red bob, sharper tongue and enviable sense of style. In two series of Mary, Queen of Shops on BBC Two, she whipped ailing businesses into shape and established herself as one of television’s most striking and engaging personalities. If online message boards are to be believed, she also – thanks to her much-discussed mid-life divorce, relationship with Grazia fashion editor Melanie Rickey and sexy combination of attitude, intelligence and eye-catching elegance – inspired happily married women up and down the land to fantasise about enjoying a sapphic interlude with her.
