Olympic gold medallist Anna Watkins has withdrawn from the British programme for this year’s Games in Rio.
The 32-year-old, who also won two World Championships, returned to training in 2015 after a three-year absence, during which she had two children.
But, after recent tests, Watkins felt she was not at the required level.
“This is not a decision that I’ve taken lightly,” she said. “I guess I would have always wondered about what might have been if I hadn’t given it a go.”
