An Olympic record performance by Charlotte Dujardin helped Great Britain remain in first place in the team dressage competition.

Dujardin's score of 83.663 was the best recorded by any rider during the first two days of dressage competition, in which the team and individual events are run concurrently.

While Dujardin is highest among individuals, the British lead the team standings with a score of 79.407. Germany, which has won seven gold medals in a row (the first two as West Germany), is second with a score of 78.845.

The Netherlands is third, while the United States team, which includes the horse owned by Ann Romney, is fifth and qualified for Tuesday's team final. Scores from that competition, also known as the Grand Prix Special, will be combined with those from the last two days to determine the team medals.

Performances in the Grand Prix Special will determine which riders compete in the individual dressage medal round on Thursday.

Dujardin and her horse Valegro recorded the best individual score over the first two days of dressage competition and the Netherlands' Adelinde Cornelissen had the second-highest score (81.687).

Germany's Helen Langehanenberg and Kristina Sprehe were third and fourth, while American Steffen Peters was sixth.
