The founder and joint chief executive of Bet365, Denise Coates, had a tax liability of £276 million last year, making her the country’s largest taxpayer last year.

Coates and family owed tax bills including their £113.2 million share of Bet365’s corporation tax bill and social security costs, such as National Insurance, and £130 million in tax from Coates’ £276.6 million income.

She is now the best-paid boss in the UK for the third year running, and Forbes magazine estimates her net worth to be in the region of $12bn (£9bn).
