Long-time Wimbledon referee Alan Mills dies, aged 88

In a statement confirming Mills had died on Thursday, the ATP described him as having "an impeccable character and integrity".

Another former Wimbledon referee, Gerry Armstrong, said: "Alan was a great influence on myself and many officials around the world. 

"He was always helpful and encouraging during the years we worked together at Wimbledon and on the ATP Tour. It was a great honour to work alongside him in professional tennis for many decades." 

Prior to his off-court role, Mills had been a player and coach himself, reaching Wimbledon's fourth round on two occasions, while he also made the third round of the French Open twice.
