Paul Tapner leads the Mitsubishi Motors Badminton Horse Trials after an eventful cross-country day on which five of the top six after dressage failed to complete.

Paul was just one second over the optimum time on the experienced 14-year-old Inonothing to take the top spot from long-time leader Mary King.

“That’s what I planned so it’s lovely when a plan comes together,” said Paul. “As I said earlier in the week when I did my charity course walks, I’ve been placed plenty of times, I’m not here to place any more.”

Paul moved up from 11th equal after dressage — and proved a real cool customer today by admitting he had a full roast dinner between riding his two horses.

Mary King holds second place with Imperial Cavalier, 2.3pen behind Paul, having held the lead for much of the day.

German accountant Simone Deitermann is third with Free Easy NRW.

“My horse was fighting me over the first 10 fences, but after the first water [The Lake], he was very very good and I could ride straight on,” she said.

James Robinson is fourth and on track to equal his previous best placing of fourth with Comanche — or even better it, as the scores are close with only one showjump down covering the first four.

Another German, Andreas Dibowski, is fifth with Euroridings Butts Leon, and Daisy Berkeley (née Dick) is sixth with the popular 17-year-old Spring Along.

Dressage leader stops

German dressage leader Kai Rüder was going well until he missed his jerk at the Outlander Bank (fence 18) and Leprince Des Bois shuffled and stopped at the log on top of the bank.

Many top Brits fared even worse — European champion Miners Frolic (third after dressage) hesitated and left a leg jumping into The Lake (fence 12), giving himself and rider Tina Cook a dunking, which Tina took in good spirits, bowing to the crowd.

Francis Whittington (fifth after dressage) was devastated to fall from Sir Percival III at the Alterian Staircase (fence 24) and Piggy French took a heavy fall when her European silver medallist Some Day Soon left a leg jumping into the Countryside Complex (fence 14).

Final runner William Fox-Pitt withdrew his second horse Seacookie, after feeling he wasn’t quite right in the warm-up.

Horse fatality

Louisa Lockwood’s ride Desert Island was put down following a fall at the corner in Huntsmans Close. Louisa did not suffer any serious injuries.

A statement from the press office soon after the accident said that an investigation into the circumstances was taking place and more information would be released when it is available.
