THE division of the assets of Sir Brian Souter and Ann Gloag’s joint investment vehicle marks the end of another chapter in one of the most successful relationships in Scottish business history.

There does not appear to be any animosity in the dividing of £600m of assets held by Highland Global Transport, given the close relationship enjoyed by the siblings since their first venture launched.

Stagecoach was founded in 1980. Having seen an opportunity in the deregulation of public transport, the siblings ran buses between Dundee and London, with Sir Brian occasionally at the wheel.

Stagecoach grew through a hungry acquisition strategy, and after floating in 1993, moved into the rail market.

Sir Brian remains chairman, and holds a 15.16 per cent stake. Ms Gloag, may not be involved day-to-day anymore, but holds 10.9 per cent of the share capital.

Together, the siblings are the largest shareholders in what is now a global transport giant with revenues of £3.9 billion.

Many businesses across Scotland and beyond have benefited from investments by Sir Brian and Ms Gloag.

It has not be revealed how the assets of Highland Global Transport have been split, but it is safe to say that brother and sister will continue to have a keen eye for investments.

Whatever the future holds, Sir Brian is unlikely to be reaching for his bus driver’s cap again anytime soon.
