The World Anti-Doping Agency (Wada) has appealed against the decision not to sanction British cyclist Lizzy Banks following a positive doping test.

Banks, 33, quit the sport last month following a 10-month case, in which UK Anti-Doping (Ukad) found her at “no fault or negligence” and lifted her suspension.

She faced a two-year ban and spent about £40,000 contesting the result, which found traces of chlortalidone and formoterol, before being cleared by Ukad in March.

Wada has told BBC Sport it lodged an appeal with the Court of Arbitration for Sport on 4 June.

Banks has represented Great Britain at the World Championships and won stages at the Giro d’Italia. She was competing for World Tour team EF Education-Tibco-SVB when she was notified of the adverse analytical finding last July.

The cyclist said formoterol was something she had taken for years for asthma, however was unable to trace the chlortalidone, a diuretic which is banned as it can be used as a masking agent.
