Manchester: The chief executive of British Cycling is stepping down, adding to the turmoil in the country’s most successful Olympic sport.

Ian Drake said in a statement released Friday by British Cycling that he will leave in April after seven years in the position.

The announcement comes at the end of a tough year off the track for British Cycling, with Shane Sutton having left his role as the national body’s technical director in April — 100 days before the Rio de Janeiro Olympics — following discrimination allegations.

British Cycling’s headquarters were visited by UK Anti-Doping officials this month as part of an investigation into allegations of wrongdoing in the sport.

On the track, Britain won six gold medals in Rio.
