Last week, billionaire Manchester United owner Sir Jim Ratcliffe complained that Britain’s billionaires were leaving as the country was “on the slide” and blamed high taxes and high immigration for the decline.

The remarks followed the departure of several of the UK’s highest earners including billionaire hedge fund founder Chris Rokos, who was reportedly moving to Greece amid fears of tax rises in the government’s autumn Budget.

Steel baron Lakshmi Mittal also moved to Switzerland since Labour came to power.

“In America they applaud people who create wealth,” Sir Jim added. “Unfortunately the UK has got a bit of a green eye towards wealth at the moment.”

Sir Jim, who is is worth around £15bn, left the UK in 2018 to become a tax resident in Monaco and was a prominent backer of Brexit and Britain’s richest man at the time of his exit.

Other departing wealthy figures include easyJet founder Sir Stelios Haji-Ioannou and Formula One driver Sir Lewis Hamilton.
