The world’s best wheelchair tennis players are set to begin battle at Queen Elizabeth Olympic Park tomorrow, but three of them had a warm up match with a very special guest.

The Mayor of London, Boris Johnson, was on hand to play a game of mini tennis with British Paralympic medallist Jordanne Whiley and South African stars Kgothatso Montjane and Lucas Sithole outside City Hall on Monday.

For the trio, the tournament at Lee Valley Hockey and Tennis Centre is a return to a familiar venue, as all three competed there during the Paralympics when it was known as Eton Manor.

Jordanne, who won bronze in the women’s doubles two years ago, said: “I hope that we’ll have lots of fans cheering us Brits on once again, just like we had at the Paralympics and I’m sure that will inspire me to another personal best performance.

“It will be so good to be back at the place where I won my bronze medal in 2012 and relive those fantastic memories.

“After reaching the last four of the NEC Masters on my debut last year I’m excited to see what the Masters holds for me this year.”

The tournament will see the eight top ranked male and female players, plus the top four quad players, battle it out to be crowned the 2014 master.
