Founder of Bet365 Denise Coates became the highest paid boss after giving herself a wage of £199m last year.
The co-founder of the bookmaking firm paid herself the record sum after the company posted profits of £525m for the 2016/2017 financial year.
The 50-year-old billionaire came from humble beginnings working in her father's bookmakers as a cashier. She started Bet365 website after borrowing £15m against the family's betting shop. Established in a portakabin in 2000 based in Stoke-on-Trent car park. Buying the domain name Bet365.com she built one of the most profitable businesses in Britain.
Forbes detailed that Coats personal fortune is $4bn (£3bn).
The company has a major stake in Stoke City Football club.
Recent concerns regarding problem gambling prompted Coats to say: "Bet365 recognises its responsibility to minimise gambling-related harm and to keep crime out of gambling".
Last year, Bet365 customers wagered $47bn up more than £10bn on the previous year.
