Emma Raducanu made almost £10 million in earnings last year as she cashed in from a series of sponsorship and endorsement deals.

The tennis star aged just 21 saw her fortune rocket up from £667,000 to £10.2million, newly-published accounts for her company Harbour 6 show.

The meteoric rise in her finances comes despite a difficult time on the tennis court in which she has failed to repeat her heroics of 2021 when she won the US Open.

But her status the UK’s brightest tennis hope has meant she has raked in a fortune from business deals.

These include working as a brand ambassador for Porsche and endorsements for big names which include Nike, British Airways, Evian, Dior, Tiffany’s and Vodafone.

The accounts show that she hold £6.3 million in cash, £2.3 million in stocks and is owed £1.6 million by debtors.

She earned so much cash that the business was hit with a £1.8 million corporation tax bill, which along with other costs meant the company was still worth more than£8 million.

The figures, covering the 12 months to the end of February 2023 have just been published by Companies House, and show she loaned herself £350,608 from the company.

Emma missed Wimbledon last year because of a wrist injury, but it is hoped she will lead the Brits charge at this summer’s event.

She has faced accusations that too much time is being spent on off court money spinning work than progressing as a tennis star.

But her management team have said this is not the case, with her agent Max Eisenbud saying she had passed up on ‘millions’ in sponsorship deals.

In 2022 he said: ‘We could have done 50 days of shoots,’ Eisenbud told The BBC’s Sports Desk podcast.
