And an interesting tidbit about former London mayor Boris Johnson's wife Marina Claire Wheeler.

So, Ms Wheeler (says Wikipedia) is of half English and half Indian Sikh descent, the daughter of BBC correspondent Sir Charles Wheeler and his second wife Dilip Singh. Her Asian ancestry goes back to the town of Sargodha in West Punjab, with her maternal family migrating to India after the partition.

She was educated at the European School of Brussels, and then in the early 1980s at Fitzwilliam College, Cambridge University, where she wrote for the student magazine Cantab. At the European School, she became friendly with Boris Johnson, the journalist and politician. Her sister, Shirin Wheeler, is an EU spokeswoman.

Ironically, her husband the former mayor Boris Johnson, is on the 'Leave' side, which believes an independent Britain will be able to contain immigration.
