Judy Murray

Kirsty Young's castaway this week is Judy Murray.

A tennis coach since she was 17, she's the current British captain of the Fed Cup, the premier team competition in women's tennis, and was herself at one time ranked 8th in Britain - achievements worth celebrating.

But what she's best known for is being the ultimate tennis mum. Both her sons have reached the top flight of the game - one as Wimbledon mixed doubles champion, the other becoming the first Brit to win the men's singles in 77 years. In the moments after Andy Murray's heroic win on Centre Court last year it was to her he turned pumping his fists and roaring - as if to say 'we have done it'.

Judy's many followers on social media know how she spends her time - countless hours travelling up and down the country coaching and working to inspire children to take up the game.

She says, 'I've always been competitive. I'm like Andy, or maybe he's like me - I wear my heart on my sleeve. And when something is great, then yep, I am right into it'.
