Ken Buchanan, Scotland's first undisputed world champion and arguably the country's greatest boxer, has died at the age of 77.
Ednews report citing foreign Reuters that the Ken Buchanan Foundation confirmed the Edinburgh native's death on Saturday, a year after his son Mark said his father had been diagnosed with dementia.
"It is with great sadness that we inform you Ken passed away peacefully in his sleep," read a statement. "RIP Ken, always a gentleman and one of the best champions we will ever see."
Having turned professional in 1965, Buchanan memorably won the WBA lightweight world title by dethroning Panama's Ismael Laguna in the scorching heat of Puerto Rico in 1970.
That same year, the Scot was the American Boxing Writers' Association's Fighter of the Year, ahead of Joe Frazier and Muhammad Ali.
