It may be one of the world’s most historic races, but the Epsom Derby is still ringing the changes 235 years after it was first held.

Once again racegoers are going through the annual ritual of choosing the perfect hat for the day and brushing up on their equestrian knowledge.

British supermodel Jodie Kidd is the face of the Derby this year and renowned chefs Michel Roux Jr and Albert Roux will serve up food on the Prince’s Lawn.

Epsom Downs Racecourse will also be selling English wine and creating a country garden seating area with a stream next to the Duchess’ Stand for the first time.

Simon Brocklehurst, owner of design company Hungdrawn, said they are in the middle of constructing the stream, but the aim is to make it look like it has been there for a hundred years.

Mr Brocklehurst said: "For us to do something so unique is an honour. It’s the first time an area has been allocated to people sitting down in a man-made English country garden."

Albert Roux said: "I am delighted to be involved with the Investec Derby as this race meeting is a major part of the British social calendar and I feel immensely proud to be showcasing our food at this prestigious event."

Philip Treacy, who has designed hats for Lady Gaga and Madonna, is the Derby’s official hat designer for a third consecutive year.

After doubt about whether the Queen could attend this year's race, it has been confirmed that she will be flying back from France on the day to attend with the Duke of Edinburgh.

Ladies' Day, which combines high fashion stakes and racing, will be held the day before the Derby. More than 125,000 people are expected during the two day festival.

A mystery tipster has predicted the winner of the Derby in chalk on a wishing well at the Amato Pub in Epsom every year since the mid-19th century.

Their pick came sixth in 2012 and third in 2011. Back in 2009 the winning horse was correctly identified for the eighth time in the preceding 12 years.
