Kate Middleton will take on Tennis Legend Roger Federer @ Secret Location to Raise Money for Charity

SPORTY Kate is to take on tennis legend Roger Federer — to raise money for disadvantaged children.

The Duchess of Cambridge, 40, and former world No1 Federer, 41, will play a friendly match at a secret location.

Kate hit a rally with British sensation Emma Raducanu, 19, last year, with the US Open champion hailing the royal’s “incredible” forehand.

Her family are friendly with Federer, a tennis teacher to Prince George, nine, and a guest at the wedding of Kate’s sister, Pippa Matthews, 38.

Kate, patron of Wimbledon All England Tennis Club, and Federer have joined up to help Action for Children and the LTA Tennis Foundation.

The royal, who trained with the England team at Twickenham when made RFU patron in February and last month went sailing with Olympic hero Sir Ben Ainslie, suggested the collaboration.

She and Swiss Federer — her mum Carole’s “heart-throb”, Kate once disclosed — will play a knockabout in East London watched by kids.

Proceeds from an open practice session of The Laver Cup — a tennis contest co-founded by Federer — taking place next month will boost Kate’s charities.

Some of the cash will fund 50 Lawn Tennis Association training programmers.

Kensington Palace said: “Her Royal Highness is passionate about supporting grassroots tennis and encouraging young people from all backgrounds to become involved in the sport.”
