Amir Khan has announced his retirement from boxing aged 35, just under three months after losing to long-time rival Kell Brook.

Former unified light-welterweight world champion Khan was stopped by 36-year-old Brook in the sixth round of their grudge match in Manchester back in February.

Brook subsequently called a day on his boxing career after the all-British bout, and Khan strongly hinted at retiring in the immediate aftermath of the defeat.

The unbeaten Albanian Florian Marku was floated as the next potential fight for Khan, but the 35-year-old has decided to hang up his gloves with a professional record of 34-6.

"It’s time to hang up my gloves. I feel blessed to have had such an amazing career that has spanned over 27 years," Khan posted on Twitter on Friday.

"I want to say a heartfelt thanks and to the incredible teams I have worked with and to my family, friends and fans for the love and support they have shown me."

He accompanied the post with pictures from his greatest nights in the ring, with images from victories over Mexican icon Marco Antonio Barrera, Argentina's Marcos Maidana and American Devon Alexander.

Khan remains one of the youngest world champions in British boxing history, having won the WBA title at the age of 22, while he is Britain's youngest boxing Olympic medalist after claiming lightweight silver in 2004, aged just 17.
