MELBOURNE, Aug ⁠4 (Reuters) - Former world champion Isaac Cooper has voluntarily ⁠stepped down from the leadership group of Australia's ‌swim team for missing a team meeting and the final night of Commonwealth Games competition, governing body Swimming Australia said on Tuesday.

Cooper's withdrawal ​from the role comes four years ⁠after the sprint specialist was ⁠sent home from a training camp for the Games in ⁠Birmingham ‌for misuse of prescription medicine and wellbeing issues.

Cooper, who helped Australia win the 4x100m medley ⁠gold medal at Glasgow, had failed to meet ​team expectations and ‌had stood down from the team's "Athlete Leadership Group", ⁠Swimming Australia (SA) ​said in a statement.

"We look forward to watching Isaac compete at this month's Pan Pacific Championships."

Cooper, 22, was not competing on ⁠the final night of the swimming ​in Glasgow, but Australia's management expect their athletes to support teammates by attending.

The Sydney Morning Herald newspaper reported Cooper was ⁠out drinking in Glasgow on the final night of competition, citing sources with knowledge of the situation.

SA declined to comment.

Cooper and his management did not provide immediate comment ​when contacted by Reuters on Tuesday.

Cooper ⁠won the 50m backstroke gold medal at the 2024 world ​championships in Doha and earned Olympic ‌bronze at the 2020 Tokyo ​Games as a 17-year-old in Australia's mixed medley relay team.
