Previously he had ranked among the UK's 25 richest people, with a net worth of £5.75 billion in 2017.
Ratcliffe was knighted in the 2018 Queen's birthday honours list.  Later that same year it emerged Ratcliffe was relocating to Monaco for tax purposes.
Pushing Britain's shale gas revolution
The billionaire has been at the forefront of the push to get fracking going in the UK since 2013-14, spending millions on exploration licences and seconding Patrick Erwin, a senior Department of Energy and Climate Change (DECC) civil servant, as commercial director at his Ineos Upstream shale startup. 
In February 2019 Ratcliffe publicly called on the UK Government to rip up the shale industry’s 'unworkable' regulations or face an 'energy crisis'. Ministers were using 'slippery back door manoeuvres to end shale” including 'absurd' earthquake limits imposed on shale gas developers, Ineos claimed. The company also warned the Government that it's 'betting the future of our manufacturing industry on windmills and imported gas', which could cause 'irreparable damage' to the UK’s manufacturing base. 
Meetings on shale gas with UK government ministers and officials
- Ratcliffe met with Stephen Lovegrove, DECC Permanent Secretary on 28 June 2013 at 3 Whitehall Place. The government's briefing notes described Ratcliffe as 'very well connected and has had a number of meetings with Ministers in various Departments and with Jeremy Heywood'. A section discussing INEOS' potential activities in shale gas was redacted from the briefing note. This meeting appeared to have been suggested to Lovegrove at a 'recent Lancastrian dinner' (held in April 2013). The focus of the meeting was 'primarily... about shale gas and the importance of supporting its development' in the UK.
