TV presenter Trinny Woodall has revealed how alcoholism and cocaine addiction turned her into a “fake, lying, thieving, cheating person”.

Two sisters who acted as personal assistants to Nigella Lawson and her former husband Charles Saatchi will stand trial in Britain today accused of using a credit card given to them by the celebrity couple to buy things for themselves.

Charles Saatchi referred to his former wife, Nigella Lawson, as “Higella” and accused her of being so off her head on drugs that she allowed their personal assistants to spend the couple’s money on whatever they liked, a court heard.
