The son of Alex Younger, the head of MI6, has been killed in an accident on a Scottish estate.

Sam Younger, 22, who was the middle child of the intelligence chief, died in the early hours of Saturday morning on a private estate in Stirlingshire, according to Police Scotland.

It is understood the Edinburgh University student died in a car crash, but police declined to give any further details, other than to say there were no suspicious circumstances.

Police Scotland also declined to name the Scottish estate where the accident took place.

Mr Younger, 55, and his wife, along with their two other children, aged 24 and 20, appealed for privacy to grieve and celebrate the life of their "wonderful, fun loving son".

Sam was a former pupil of Dulwich College in south London, where he played rugby for first XV.
