UK bookmaker Ladbrokes has extended its partnership with Australia’s Melbourne Racing Cup (MRC), which includes naming rights for a number of popular horse races.

Under the new deal, Ladbrokes will assume naming rights of Caulfield Guineas Day, including the famous AUS$1m Group 1 classic thoroughbred race and the renamed Group 1 Ladbrokes Stakes (formerly Caulfield Stakes).

Sandown Racecourse will continue to be named Ladbrokes Park, with up to 1,000 Ladbrokes customers given free entry to Caulfield Racecourse for the Guineas Day racing on October 8th.

Ladbrokes will also continue its association with Victoria’s sole Group 1 race for two-year olds, the $1.5m Group 1 Blue Diamond Stakes and its series of preludes and previews, as well as the Group 1 C.F. Orr Stakes and a portfolio of 19 group and listed races run at the MRC’s three tracks.

In October 2015, Ladbrokes replaced rival William Hill as the official corporate bookmaker and sponsor of the Melbourne Racing Cup.

Melbourne Racing Cup CEO Brodie Arnhold, said: “Since our relationship formally began not even a year ago, Ladbrokes have proven to be a fantastic partner for the club, which we’re thrilled they will continue to be.

“The commercial investment is obviously incredibly valuable to an organisation like ours, but the willingness to innovate together and integrate into various areas of our business outside of race naming rights shows that Ladbrokes has a great care and passion for the sport of racing and its sustainability.

“I once again thank Ladbrokes for their ongoing support; we look forward to continuing to work alongside them.”

Ladbrokes Australia’s head of media Roger Oldridge added: “This is a significant investment in the Melbourne Racing Club and the industry as a whole and a commitment to both which we see as vital for the long term sustainability of all parties.

“We're not in the business of divulging exact figures, whether it is specific punters’ bets or a deal of this magnitude between two very strong organisations, suffice to say we are heavily invested in the MRC and in racing.”
