David and Samantha Cameron enjoy winning bet on Sam’s old aide Isabel Spearman at Newbury races 

David and Samantha Cameron enjoyed a day at the races today as they backed former aide turned jockey Isabel Spearman at Newbury.

Spearman, who was Samantha Cameron’s aide while her husband was Prime Minister, won The Injured Jockeys Fund Charity Race at Newbury.

Although David Cameron’s time as Prime Minister ended after he picked the wrong side in the EU referendum, luck was in his favour today as he bet on his friend Spearman to win.

The former Tory leader said the day was ‘absolutely wonderful’.

‘She’s a very old friend and we came along to cheer her on,’ he told the Racing Post. ‘We had no idea she was going to win but luckily my wife said to put a bet on, so happy days.’

He watched on in the glorious sunshine with a pair of red binoculars, matching his wife’s dress made by Cefinn, Samantha Cameron’s clothing label.

While Spearman worked for Samantha Cameron she was in charge of her diary and helping choose her outfits.

Spearman said her horse today was ‘incredible and I was very lucky to ride him’.

The race she won today raised a huge £50,000 for charity.
