Newmarket has been long been known as the home of British horse racing but until now no-one has ever really put an accurate price on how much the industry brings to the area.

The horse racing world has been centred on Newmarket for 400 years and at the peak of the season up to 3,000 horses are training in the area.

The economic impact that the horse racing has on the region will be revealed in a new report due to be published this morning.
Newmarket is known as the home of British racing with thundreds of horses being trained at stables around the town.
The report has been commissioned by Forest Heath District Council and a trade organisation representing trainers, owners, jockeys and stable staff.
Newmarket racing stable Godolphin have announced that some of the horses, including St Leger winner Encke, banned from racing due to the Mahmood Al Zarooni scandal will soon return to action.
Encke has not been seen since he foiled Camelot's bid to land the Triple Crown at Doncaster in 2012 but will go back into training with Charlie Appleby in Newmarket, with the intention of running in Europe later this year.
Steeler, who joined Godolphin from Mark Johnston after finishing third in the Racing Post Trophy in 2012, is in line to run on Thursday at Meydan, while Certify, unbeaten as a juvenile in 2012 with wins in the May Hill and the Fillies' Mile, will reappear later in the Carnival.
Twenty-two former Al Zarooni-trained horses were suspended from racing between April and October last year after testing positive for banned anabolic steroids.
Al Zarooni was banned for eight years.

Newmarket racehorse trainer Gerard Butler has been banned from the sport until 2018 after admitting giving some of his horses an anabolic steroid.
Butler told a disciplinary hearing that he had treated some of his horses with a substance that contained the steroid under the advice of his vet.
But he later admitted seven charges and has been disqualified by the British Horse Racing Authority.
A ruling on Newmarket horse trainer Gerard Butler's use of steroids on horses in his care has been adjourned until next week.
The trainer admits using steroids on nine horses tested back in February, but claims it was done under advice from vets.
The British Horseracing Authority disciplinary panel hearing has now concluded, with the result expected next week.
Controversial plans to build new homes on the edge of Newmarket have re-emerged again.
Last year plans to build 1200 properties on Hatchfield Farm were thrown out at a planning inquiry, which campaigners thought was the end of a 4 year battle.
Now the landowner Lord Derby has submitted scaled down proposals for 400 new homes.
He says the Suffolk town needs more affordable housing. However campaigners claim it would damage the town's horseracing industry and make traffic congestion unbearable.
