Scotland's richest people got richer over the last year, with a record number of billionaires.

The number of Scots among Britain's wealthiest people reached a 10-year high, with 78 joining the ranks in the 2013 list, compared to 74 last year.

The number of Scots billionaires has grown from two to six in two years, with Mahdi al-Tajir, head of the Highland Spring mineral water firm named as Scotland's richest person, worth £1.65billion.

The 81-year-old ex-UAE ambassador to the UK has a 24,000-acre estate near Gleneagles, Perthshire, and splits his time between there and London.
