Jones, who has been racing Ginetta across Europe for nine years, has joined forces with Sadler's Peaky Blinder Irish Whiskey for the 2020 season, which begins at Donington Park on 28 and 29 March.
The 24-year-old's G55 GT4 SuperCup has been wrapped in Peaky Blinder branding, he will have access to a branded BMW M4, which Sadler's Brewing Co. upgraded to his specifications, and a branded hospitality bus is also scheduled to be present on race days, equipped with the Peaky Blinder range of spirits and craft beer.
Chris Dew, marketing manager at Sadler's Brewing Co., said: "Stepping into the fast lane with Declan Jones at the BTCC weekends provides an incredible platform to showcase Sadler's Peaky Blinder Irish Whiskey to a huge audience of more than 40,000 trackside spectators and more than a million at-home viewers worldwide."
Declan Jones added: "I'm very happy to be working with Sadler's Brewing Co. during the 2020 season. I come from a competitive family and this sponsorship has allowed me to approach the first race with the added confidence that comes from having the backing of such a notable brand."
