EasyJet founder Sir Stelios Haji-Ioannou and his family are reported to have fallen down more than 20 places down the latest Sunday Times Rich List following the Brexit vote.

Their worth fell by £640 million over the previous year to £1.95 billion, placing them 64th in the annual rankings of the UK’s richest people, a fall from 41st place.

The Rich List said: “The morning after the referendum easyJet’s shares nosedived – and have yet to recover.

“The Athens-born entrepreneur and his family have a 34% stake in the budget airline worth £1.29 billion, a drop of £770 million since last year.”

Haji-Ioannou stepped down as chairman of the budget carrier in 2002 and has since diversified with his London-based easyGroup businesses, including easyHotel, which after its float is valued at £88.9 million, putting the family stake at £49.5 million.

EasyGroup has received £385 million in dividends from easyJet In the past five years, while its Stelmar shipping company was sold to a British firm for £470 million, netting it about £94 million.

“But generous dividends and the rallying share price of the hotel operation cannot offset the losses to Monaco resident Haji-Ioannou from the airline’s plummeting stock market value,” the Rich List said.

Philip Meeson, executive chairman of Jet2.com and Jet2holidays owner Dart Group, also suffered a fall down the list as shares in the Leeds-based business plummeted following the Brexit vote. His worth is estimated to have dropped by £90 million to £296 million, placing him in 399th place on the list, down from 290th a year earlier.

However, Virgin Group founder Sir Richard Branson and his family saw their fortune rise by £345 million to £4.865 billion, despite dropping down the list from 19th to 23rd place this year.

“Last year he sold his 30% share in his Virgin America airline for £540 million and among other holdings he has stakes worth £330 million in Virgin Atlantic, £530 million in Virgin Money and £180 million in Virgin Active,” the Rich List said.

“His Virgin Trains, run in partnership with Stagecoach, the transport operator founded by Sir Brian Souter and his sister Ann Gloag, is also worth £100 million.

“Cash and properties valued at £1.1 billion take Branson to £4.865 billion this year.”

Skyscanner co-founder Gareth Williams is a new entry at 525th place with £215 million following the sale of the business to Chinese firm Ctrip.
