The chair of the transport company Stagecoach has made a donation worth more than £100m to a foundation he set up.
Sir Brian Souter said he had given £109m in shares to the Souter Charitable Trust, which he established with his wife Elizabeth in 1992 after his investments performed well.
The Scottish-based charity has given more than 13,000 grants worth more than £98m over the past 13 years and particularly supports projects for the relief of human suffering.
Souter said: "Given the excellent performance of Souter Investments, I have today gifted 28 per cent of its shares to the Souter Charitable Trust. I estimate that the value of this shareholding is £109m.
"Our total portfolio, excluding Stagecoach, increased in value by 9 per cent per annum over the 12 years ended March 2019. This compares against a 5 per cent annual return on UK-quoted equities over the same period."
