Kelly, 27, has announced she is expecting her first child with husband Ed and is unlikely to return competitively to the saddle.

"I will not be returning to the weighing room this season and in all likelihood not at all," she said. She made history with a Grade One win on Tea For Two at Kempton in 2015.

Kelly, from Devon, followed up with another top-level victory on the same horse, trained by stepfather Nick Williams, at Aintree's 2017 Grand National meeting.

The previous month she had been unseated by her mount when becoming the first woman to ride in the Cheltenham Gold Cup for 33 years.

Victories at the Cheltenham Festival came aboard Coo Star Sivola and Siruh Du Lac, with hurdler Agrapart another notable partnership.

Kelly, who has been a pundit for BBC Radio 5 live at Cheltenham and Aintree, plans to stay involved in racing and has a new bloodstock business with her husband.

"I hope to continue working within the racing media, something I've always enjoyed and am passionate about," she said. "I'll really miss race riding but won't miss those saunas. It's been a dream. Thanks to all."
