Her score of 84.200 put her well ahead of Swedish runners-up Patrik Kittel and Delaunay on 80.910 while Germany’s Jessica von Bredow-Werndl and Unee BB finished in third place on 80.845.

Werth only had a two-day turnaround after winning the previous leg of the series with Don Johnson at Neumunster in Germany last weekend but managed to maintain her sublime form to take a second victory in as many competitions.

“So I asked my rider at home to prepare Emilio in the right way - and I think she did that,” said Werth.

“I realise now that he needs more training because he didn’t always know what to do and we had two mistakes, in the pirouette and tempi changes."

Werth also confirmed that Emilio will be used at the last qualifying leg in ’s-Hertogenbosch in The Netherlands in two weeks’ time.

Her preferred ride for the FEI World Cup Dressage Final in Omaha in Nebraska in the United States next month is her Olympic mare Weihegold, but she now considers Emilio a strong reserve. 

Werth, who has won six Olympic gold medals during her career, now holds an emphatic lead at the top of the World Cup Standings.

She sits top on 80 points, 25 clear of compatriot Kristy Oatley who occupies second on 55.

Great Britain's Carl Hester lies in third on 54 points.
