Nigel and Vanessa Lawson divorced in 1980, when Nigella was 20. They both remarried: her father that year to a House of Commons researcher, Therese Maclear (to whom he was married until 2008), and her mother, in the early 1980s, to philosopher A. J. Ayer (they remained married until her mother's death). As her father was at the time a prominent political figure, Nigella found some of the judgements and preconceptions that were formed about her frustrating. She has attributed her unhappiness as a child, in part, to the problematic relationship she had with her mother.
