25 SIR KEITH MILLS
Loyalty cards 2018: £160m 2017: £160m (23rd=)
Born in Brentwood, Mills made his money from loyalty cards – first Air Miles, taken over by BA in 1994 and later the Nectar card, which he sold in 2007 netting £160m. But sport is his passion. He was a leading backer of Sir Ben Ainslie’s unsuccessful America’s Cup sailing campaign last year. This was the loyalty scheme entrepreneur’s latest venture in the sporting arena, having previously organised the Invictus Games. He was also deputy chairman of the organising committee for the London Olympics. His other assets include around £2m of company assets and a recent £2.5m investment in video messaging app Wordeo. He settled a claim against Coutts Bank where he had £73m of his wealth tied up in AIG Bonds, and had been seeking £8m in damages. So we still value Mills at £160m for now.
