Polly Stockton will take her Irish sport horse Regulus to the HSBC FEI European Eventing Championships 2011 in Luhmühlen (25-28 August) rather than Westwood Poser who has suffered a slight injury in training.

The squad is now composed of Laura Collett and Rayef, William Fox-Pitt riding Cool Mountain, Piggy French and Jakata, Mary King with Imperial Cavalier, Polly Stockton riding Regulus and Nicola Wilson and Opposition Buzz.

Lucy Wiegersma and Francis Whittington are the reserve riders with Woodfalls Inigo Jones and Sir Percival III respectively.

The four riders to compete in the team competition at the championships will be selected at event, following the trot up.

The remaining two horses and riders will represent Britain as individuals; their results will not affect the overall team score.
