Mum to two former world number one tennis players, Judy Murray is calling on the government to provide coaches at public courts, to make the game less elite. The tennis coach is also calling for a specialist PE teacher in every primary school, to promote physical activity and create sports stars of the future. She says: “Helping our kids to develop physical literacy, for me, is just as important as numerical and alphabetical skills.”As tennis fans enjoy Wimbledon, Judy - who was rooting for Jack Draper, who her son, Sir Andy, has been coaching, is now backing top seed Jannik Sinner to win, after Draper withdrew with an arm injury - says the game “needs to be affordable”.The former Strictly and Celebrity Masterchef star says: “The perception of tennis for many people is that it's difficult to access, difficult to do and expensive. Not everybody's got money to pay for coaching.I think for us to really open the game up more ,or put it into places where it doesn't exist, it needs to be accessible.”Judy, 66, who lives in Scotland, continues: “I want the government to provide coaches at public tennis courts. Loads of people take up tennis at this time of year because of Wimbledon and we need to catch them and keep them. The key? Show them how it’s done.‌“If you're going along to play anything for the first time or the second time and you quite enjoy it, it's good if there's somebody there that can actually show you what to do. You need people driving activity on a regular basis and creating a community hub or club around them. That's the way that you retain people in the game.”Surrounded by sport this summer, with Wimbledon, the World Cup and the Commonwealth Games, Judy wants to harness people’s enthusiasm for physical activity - starting in the classroom. She says: “I would like to see, certainly in Scotland, them putting a PE teacher, a specialist, qualified, PE teacher, into every primary school. That would be a legacy from all of these summer activities that would have an effect on every child in a primary school.“If you can do that in primary schools and foster a love of exercise and being physically active, it will stay with kids. It will help them to develop the coordination skills that underpin all sports at a young age. It's too late to wait until secondary school. If I had a message to any politician that has a decision-making position, I would say ‘put a PE teacher in every single primary in the country.’‌Scotland crashed out of the World Cup in the group stages, but if PE was given more prominence in school, Judy says it would help create football’s stars of the future. She says: “If we develop more of those skills at a young age and we improve on them as they get older, we will develop more skilful athletes, footballers.”Judy is speaking as part of a partnership with household cleaning products company Dr Beckmann, which has seen her unveil a giant 'Murray Mound' created from discarded white garments on London's Southbank. It symbolises the estimated 440 million items of white clothing which the firm says Brits discard annually.Keen to illustrate the need for recycling, Judy says: “Too many things are discarded without thought. That can have a huge impact on the environment. We all need to take more responsibility and recycling, reselling or taking better care of white clothing is one more thing that needs to be addressed.”‌Made an OBE in 2017 for services to tennis, women in sport, and charity, as part of her drive to promote healthy activity, Judy is also keen to reduce our reliance on screen time - particularly for children. She says: “We are leading more sedentary lifestyles because of screens and children most certainly are.“I say put the screens down, get outside, get active. Pick up a tennis racket. It's not just the physical and mental health aspects that come with being active, it's actually the life skills that you can develop through being part of a sport that help you to deal with life in the future.”A devoted mum, Judy has been a stalwart supporter of both her sons’ tennis careers, which saw Sir Andy win three majors - the 2012 US Open and Wimbledon in 2013 and 2016 - while doubles player Jamie became the first Brit to win a major title at Wimbledon for 20 years, when he won the mixed doubles with Serbia's Jelena Jankovic in 2007.‌They are also the first brothers to simultaneously hold ATP world No.1 rankings in singles and doubles, in 2016. But watching them play could be gruelling for their mum. Judy says: “I'll tell you what it's like watching my boys play tennis. It's like a series of mini heart attacks and severe nausea all going on at the same time. And, quite frankly, I'm surprised I'm still alive after all these years and all these roller coasters. I had a double whammy of it, because I had both of my kids playing, one playing singles, one playing doubles.“I have to say it's very stressful and I think it becomes even more stressful when they get to the top of the game, because on the way up it's actually more exciting. It's still nerve-wracking, but once you're at the top, everybody's trying to knock you off and there's huge media attention, fan expectation. It's not so much fun at the very top.”Judy will be back at Wimbledon next week watching Jamie play in the invitational men's doubles for retired players. Meanwhile, being a coach, she says, has made her a better mum. She says: “When the boys became pros, I wasn't their coach, I was managing a lot of the things around their careers.‌“My feeling always, as both a parent and a coach, is that you are preparing them to be able to do life without you. So the more you can help them to understand how to look after themselves and take responsibility, you know, the better. Whether that's packing your own school bag, choosing your own lunch, helping in the supermarket, understanding how much things cost. Instead of doing everything for them, try to make them do things for themselves.”However, tough talking Judy says she’s a softie as a grandma to her five grandchildren. She says: “I think I'm probably not as firm as I was with my own kids with my grandkids. I am a bit of a pushover granny, but I'm a very active granny. I'm not going to teach them how to play tennis, I'm going to teach them how to dance.”*Dr. Beckmann has launched The Washing Line, a dedicated laundry hotline (+441618412861), offering expert advice on tackling stains, dullness and discolouration this Wimbledon fortnight.
