Boris Johnson’s mother has died aged 79.
Charlotte Johnson Wahl, a professional painter, died “suddenly and peacefully” in a London hospital on Monday.
Johnson Wahl suffered from Parkinson’s disease.
In an interview in 2008, she said: “I try to paint every day if I can, even though I often have to go to the hospital.
“I still manage to paint, even though my arm will suddenly make a movement that is completely involuntary and almost makes me cry.”
Her artistic interests varied, but she made a name for herself as a portrait painter, with models like author Jilly Cooper and actress Joanna Lumley.
Johnson Wahl studied English at the University of Oxford, but suspended his studies to travel to the United States with Stanley Johnson.
The two were married in 1963 before she graduated as the first undergraduate married woman at her university – Lady Margaret Hall.
She and Stanley had four children – Boris, journalist Rachel, former MP Jo and environmentalist Leo – before divorcing in 1979.
In 1988, she married the American professor Nicholas Wahl.
They lived in New York City, where she turned to cityscape painting and held a sold-out exhibition in 2004.
She returned to London in 1996 after Mr Wahl’s death.
Mr Johnson once described his mother as the “supreme authority” of the family and gave her credit for instilling in her the equal value of every human life.
Reacting to the death of Johnson Wahl, Labor leader Sir Keir Starmer said: “I am very sorry to hear of the loss of the Prime Minister. My condolences to him and his family.”
