Painter Charlotte Johnson Wahl, the mother of British Prime Minister Boris Johnson, has died aged 79.
Wahl died "suddenly and peacefully" at a London hospital on Monday, according to a death notice in The Times of London.
Boris Johnson once described his mother as the "supreme authority" in his large, close-knit family. She was a successful painter of portraits and landscapes.
Wahl and first husband Stanley Johnson divorced in 1979. She later married American academic Nicholas Wahl, who died in 1996.
