After four weeks of drama, art collector Charles Saatchi has finally announced he is divorcing his wife, celebrity chef Nigella Lawson.

The cracks in their marriage became public after the 70-year-old millionaire was photographed with his hands around her throat at an upscale restaurant last month. The photos showed Saatchi grabbing her neck with his hands in a fit of rage. At the end of the meal the 53-year-old chef, who has both men and women drooling over her recipes, had left the restaurant in tears. Saatchi had received a caution from Scotland Yard after the row.
