Operator Betfair has agreed a partnership which will see it integrated on the Racing Post app.
Customers will be able to place bets on greyhound and horseracing with Betfair’s Sportsbook, directly on Racing Post’s free iOS mobile app and website.
Betfair joins fellow Flutter Entertainment-owned Paddy Power, as well as William Hill, Ladbrokes Coral and Bet365 in joining the app.
Racing Post Commercial Director Sam Houlding said: "We have a long and successful partnership with Flutter Entertainment in print, online and retail and are delighted we continue to grow the ways in which we work together and add value to each other’s businesses."
Rich Hayward, Betfair Commercial Director, added: "We know the value of the Racing Post and how it has been the cornerstone of the greyhound and horseracing betting industry for years.
"Partnering with Racing Post’s mobile and desktop products broadens the options for both Betfair and Racing Post customers.
"We know our customers continue to use mobile more and more and the Racing Post app provides a superb experience for those wishing to bet on horseracing and greyhounds."
It’s been a busy past few months for the Racing Post, which extended its international horseracing to cover 15 new territories in September, while in August, the publisher launched its new B2B horseracing trading solution, AllSported.
