"Raised on benefits, secondhand clothes and food parcels, Emily Thornberry joined the Labour party at the age of 17 because she believed that “it wasn’t fair that things had been so hard”.
She went on to become a human rights lawyer and in 2005 a member of parliament, when she was elected by a majority of under 500 votes to represent Islington South and Finsbury, a north London constituency with large disparities in wealth which has sometimes been seen as a metaphor for New Labour.
While her mother was a teacher and her father an international lawyer who taught at the London School of Economics, Thornberry has described a far from comfortable childhood after they divorced when she was seven and she and her siblings moved to social housing in Guildford with her mother, who later became a Labour councillor and mayor."
