Two Gloucestershire businessmen associated with engineering giant Renishaw have once again appeared in the Sunday Times Rich List.

Sir David McMurtry, the co-founder and executive chairman of the Wotton-under-Edge based company, has risen to 93rd place on the Rich List. He is now worth £1.78bn - up £848m in the last year.

John Deer, the 83-year-old non-executive deputy chairman of Renishaw engineering, was ranked 195th on the list after his wealth rose by £383m last year, taking his overall worth to £823m.

In March, Sir David and Mr Deer, who set up the FTSE 250 business nearly 50 years ago, opted to sell their combined 53 per cent holding in Renishaw to "secure the future" of the firm.

Renishaw makes key components for aircraft and cars, as well as hi-tech surgical equipment.

The Sunday Times Rich List is a list of the 1,000 wealthiest people or families resident in the United Kingdom ranked by net wealth.

The Ukranian-born oil and media magnate Sir Leonard Blavatnik topped this year's Rich List, having seen his fortune swell by £7.2bn to £23bn.

He took the top spot from Sir James Dyson, whose wealth rose by only £100m to £16.3bn, leaving him in fourth place.

There are now a record 171 billionaires in the UK, with their wealth rising 21.7% during the pandemic to £597.2bn.
