Nick Skelton, who became Britain's second-oldest Olympic gold medallist with victory in the individual show jumping at Rio 2016, is to retire.

The Warwickshire rider, 59, will compete for the final time at May's Royal Windsor Horse Show on Big Star - the horse on which he won Olympic gold.

Skelton was competing at his seventh Games - 16 years after a broken neck forced his initial retirement.

"This sport has given me more than I could have ever hoped," he said.

"It is such a difficult decision to make, but I'm not getting any younger and it is nice for the two of us to end on the highest note possible.

"Thank you to all of the incredible friends and fans for your support - we are truly appreciative and humbled.

"And lastly, thank you to all of the horses I've ridden. You have provided me with opportunities one could never have imagined."
