Queen Camilla embraces Zara Tindall at Ascot as her pick for best-turned-out horse goes on to win

Camilla selected Talk Of New York as the best-turned-out horse, and the colt went on to claim the Queen Elizabeth II Stakes. She was all smiles as jockey William Buick received his trophy on behalf of trainer Charlie Appleby. Andrew Parker Bowles, her ex-husband, was seen in the Royal Box. British Champions Day carries total prize money of £4.35 million, making it the wealthiest race day in the country.

Saffie Osborne, the first woman to ride a British Classic winner, described meeting Camilla as 'a real honour'.

Camilla also took a moment to congratulate Camilla Froggatt, aged 14, on her victory in the pony race.

Zara Tindall, a London 2012 Olympic silver medallist, handed Ruan Moore the Sprint Stakes trophy.
