Michael Whitaker has been suspended from competition by the International Equestrian Federation (FEI) for an alleged doping offence.

Traces of the hormone altrenogest, which is found in Regumate given to in-season mares, were found in a sample taken from Mr Whitaker's stallion Tackeray at La Baule on 14 May.
