“As kids will be, she was very excited about it. But she was told: ‘No, you have not earned that’.”There were times when she was forced to go to tournaments or sessions carrying her kit in a black bin bag.”His behaviour was particularly unpleasant if he felt they had performed badly in tournaments. “When Nephe got to about the same age, he started with her as well.”Over the years, he continued to push these girls in their tennis training and he also involved other professional coaches to help them.”Mr Povall said that, when Monaei turned 11, he took her out of school. She was home-schooled then to give her more time for tennis training, something that happened when Nephe turned 11.”He subjected them to a tough, rigorous and demanding training schedule of stretching, physical exercise and technical tennis training,” he said. “In itself, there is nothing wrong with that. We all know, or have been ourselves, pushy parents, and where there is a child who shows talent then it is not surprising or wrong that their parents should encourage them, discipline them and help them make the very best of that talent.”It is right to say that both girls had some success as junior players. Any of us who are parents, we all do the same: ‘no TV until you do your homework’, for example. The girls were forced to run around tennis courts for hours on end.When Nephe De’Viana, now 19, was given a new tennis bag as part of sponsorship deal, her father said she “had not earned that” and was forced to carry her kit in a black bin bag to “humiliate” her.De’Viana allegedly called the girls, “fat” and “lazy c—s” when they were “as young as nine or 10” if he felt they were not training hard enough.David Povall, prosecuting, said: “It is the Crown’s case that, over a period of years, he made the lives of his two daughters miserable in a variety of different ways, but primarily around his ambition that they should be rich, famous and successful tennis players.”John De’Viana was in a relationship with a lady called Michelle Horne. They had two daughters, the older is Monaei, who was born in July 1995, and the younger daughter is Nephe, who was born in June 1998.

It went beyond the mother of the Murray brothers, who was a demanding parent and got them to the very highest level in tennis. Want the best of The Telegraph direct to your email and WhatsApp?

In other words, this was not an occasional blow-up, a loss of temper. Every parent loses his or her temper sometimes.”But, as far as their lives were concerned, this was relentless, from 5.30 in the morning through to going to bed when they finished training and stretching.”Mr Povall said the girls were “being deprived of food at lunch time, not being allowed to eat the packed lunch they were given because they were not trying hard enough”.”One of the girls was dragged off an exercise bike because she was timing her session with her phone rather than a watch,” he added.”His obsession with their success meant that this sort of behaviour, this sort of barracking he gives was constant.”Mr Povall said the abuse ended when De’Viana split up with Ms Horne in 2011, adding that “very shortly after they split, both girls, despite their success, gave up tennis”.Nephe told the court how her father made her run around a court for up to seven hours without a break in a bid to make her a star. “The best examples of the sorts of things they experienced were a daily torrent of verbal abuse, that they would be called ‘motherf—-r’ and ‘c—s’ and ‘fat, lazy c—s’ by their father when he was dissatisfied with the way they were training.”That they would be subjected to physical assault, particularly Nephe: he would take her out of sight if he was unhappy with her and kick and slap her.”That there were occasions when he was serving balls at them in order to punish them for the way they had trained poorly.”That he would do things in order to humiliate them as punishment if he was cross with them.”Nephe, for example, a talented young tennis player, got some sponsorship and got a rather smart tennis bag. A tennis coach assaulted and verbally abused his daughters in his obsessive drive to turn them into Wimbledon champions, a court heard.John De’Viana, 55, took the girls out of school to enforce gruelling all-day training regimes on them, it was said.The girls were made to practise from 5.30am until they went to bed and he would stop them having meals if he thought they were not trying hard enough, Snaresbrook Crown Court heard.Monaei De’Viana, now 21, claims her father spat at her as she was driven back from a tennis tournament “because he considered she had not performed as she had ought to”. When Nephe De’Viana, now 19, was given a new tennis bag as part of sponsorship deal, her father said she “had not earned that” and was forced to carry her kit in a black bin bag to “humiliate” her “John De’Viana behaved in a way that went so far as child cruelty as the law defines it, that is, he assaulted or ill-treated his children over time so as that the cumulative effect was likely to cause them unnecessary suffering or injury to health.”He did that, on the Crown’s case, by way of physical assaults and mental abuse of those girls, relentlessly over a period of years.”Each of them suggests that, perhaps with Monaei it was more verbal, causing her suffering by way of a constant stream of abuse, whereas with Nephe, he was more physical.”They both say that, on occasions, they were forced to run round and round the tennis courts. Nephe said that went on for hours at a time. “Mr De’Viana had a background of competing in karate at quite a high level and, as his eldest daughter Monaei got older and got into primary school, he started to train her in tennis and from quite a young age was taking that quite seriously, coaching her himself for some hours of the day.
