World heavyweight champion Tyson Fury announces retirement from boxing

Tyson Fury has announced his retirement from boxing.
The world heavyweight champion revealed the news in an expletive-laden post on Twitter.
He wrote: “Boxing is the saddest thing I ever took part in, all a pile of s***, I’m the greatest, & I’m also retired, so go suck a d**k, happy days.”
Fury, 28, hasn't fought since beating Wladimir Klitschko to claim the WBA, WBO and IBF titles last November.
He agreed to a rematch with the Ukrainian in July but called it off weeks before due to an ankle injury.
A new date was set for October but Fury withdrew again last week citing mental health issues.
It later emerged he had tested positive for cocaine at the end of September.
