The millionaire MP for Meriden abandoned her controversial injunction, which had already incurred legal fees of £60,994, after a judge ruled it was “not necessary or proportionate”.
Mrs Spelman’s 17-year-old son Jonny, who has played under-16s rugby for England, said he was “deeply sorry” for taking the drugs, banned under anti-doping rules.
In a joint statement, Secretary of State for Environment, Food and Rural Affairs Mrs Spelman and her husband Mark, said Jonny had been attempting to recover from a serious injury.
They said: “Our son, who was then aged 16, was injured in September 2011 and took some widely available drugs in order to aid his recovery. The substances are, however, banned under anti-doping rules. He has made a voluntary statement to the RFU and is now subject to their disciplinary process which is still ongoing.
“Our son knows that taking a banned substance can never, ever, be right and he is deeply sorry for the mistakes he has made and is determined to learn from them.”
