(Reuters) - Double Olympic champion Mo Farah was given a legal dose of a controversial supplement before the 2014 London Marathon, but the treatment was not properly recorded, the doctor who gave him the injection has said.

Dr Robin Chakraverty, former chief medical officer at UK Athletics, told British legislators he injected Farah with 13.5 millilitres (ml) of L-carnitine prior to his London Marathon debut but had "forgotten" to record it in the necessary forms.
