Nathan Robertson, widely regarded as Britain's greatest-ever badminton player, has announced his retirement.
The 35-year-old, an Olympic silver medallist alongside Gail Emms eight years ago, has made the decision following his failure to qualify for London 2012.
He revealed the news on his Twitter account.
Robertson wrote: "So I can now officially say. I AM RETIRED.... Thank you to everyone who supported and helped me throughout my entire career.
"The truly special people already know how thankful and respectful I am of them. I leave with great memories and even better friendships.
"I now look forward to a summer of rest and retirement celebration, my home bar is open 24hrs a day people ;-). #proud #memories."
Robertson's announcement is not a surprise as he had always intended to bow out on a high after this summer's Olympics. But after choosing to focus on mixed doubles only, his hopes of competing in London with new partner Jenny Wallwork were crushed by the rise of youngsters Chris Adcock and Imogen Bankier.
The British Olympic Association confirmed last week that Adcock and Bankier, last year's World Championships runners-up, would represent Team GB at Wembley.
Robertson will be best remembered for his formidable mixed doubles partnership with Emms. As well as claiming silver at Athens in 2004, Robertson and Emms won the All England Championship in 2005 and world and Commonwealth Games titles in 2006.
Robertson also rose to fourth in the men's doubles world rankings and twice won European Championships silvers with Anthony Clark. Domestically, he won a remarkable nine mixed doubles titles and six men's doubles crowns at the English National Championships with various partners.
