A sponsorship deal between the British Champions Series and Qipco has been extended until 2024.
In 2011, Qipco, a private investment firm based in Qatar, became the title sponsors of the series which comprises 35 flat races run between May and October.
Their involvement has resulted in prize money being increased by 50% over a four-year period, and the new deal is believed to be worth more than £50m.
Jockey Ryan Moore currently heads the 2015 standings after winning three of the opening seven races.
