GB dressage Paralympians maintained their run of success with team glory and three individual golds at the European Championships in Hungary.
Tustain was among the gold medallists in Hungary
Sophie Christiansen, Debbie Criddle, Lee Pearson and Nicola Tustain retained the team title they won in 2001.
It means GB remain Paralympic, World and European team title-holders.
Christiansen also claimed golds in the grade Ia individual dressage and freestyle events, while Tustain won grade II dressage gold at Soskut.
Triple Paralympic gold medallist Lee Pearson, riding Blue Circle Boy, won a pair of silver medals in the grade III dressage and freestyle events, finishing second to German Betinna Eistel in both disciplines.
As a grade I rider taking part in grade III events, Pearson was competing against riders with a lower level of disability than himself, making his pair of silvers in Hungary all the more impressive.
Tustain from north Wales also took freestyle bronze on her horse Prinz Heinrich, while Criddle from Somerset, riding her new mount Pompidou, took bronze in the grade III freestyle event.
Elsewhere in the British squad, Michelle Crunkhorn finished fourth in the grade IV individual dressage, Jo Pitt missed out on the medals in the individual grade II events, while Anne Dunham withdrew from the competition.
GB chef d'equipe and world class performance manager for British Paralympic dressage David Hunter said: "We're delighted.
"It's been a bit of a testing event, but the results were very encouraging and the heat has provided us with some good training for Beijing."
