Four Britons in Fatal SOuth Africa Minibus Crash

The accident happened at Thabazimbi in the Limpopo district of the country on Wednesday, the Foreign Office said.

Two other family members injured in the crash are being treated in a Johannesburg hospital.

A Foreign Office spokeswoman said: "We can confirm the deaths of four British nationals in a road traffic accident on 20 August.

"We are still seeking clarification about the accident from the South African authorities."

The Foreign Office confirmed Brenda Bonham Carter and Francis Kirkwood were among those killed.

The driver of the minibus in which they were travelling lost control after a tyre punctured and it overturned, killing four passengers and leaving at least two others injured.

Marcus Egerton-Warburton, a 14-year-old Eton schoolboy, was one of the four people killed in the accident. His mother, Fiona Bonham Carter, 51, a cousin of the actress, scrambled from the wreckage with a broken collar bone while his older brother, Piers, 16, escaped with whiplash.

Fiona’s mother, Brenda Bonham Carter, 74, and step-father Francis Kirkwood, 75, also died. The fourth victim was Kay Boardman, 54, the wife of Fiona’s brother, Graham, 48, who was also in the minibus.
