WITH BRITAIN SHIVERING UNDER SUB-ZERO TEMPERATURES, MEMBERS OF THE BRITISH WATER SKIING CLUB HAVE FOUND A NEW "WINTER SPORT" - AND A NEW WAY OF KEEPING WARM. THEY HAVE STARTED SKIING OVER FROZEN RUISLIP LIDO, NEAR LONDON, ON THEIR WATER SKIS.

AMONG THOSE TAKING PART YESTERDAY (SUNDAY) WAS M.JEAN PIERRE DELCUVE OF NAMUR, BELGIUM, A EUROPEAN WATER SKI CHAMPION. HE TRIED "TWISTING" AND JUMPING WHILE BEING TOWED ALONG BY A LAND ROVER. IT WAS THE FIRST TIME HE HAD ATTEMPTED THIS - ON ICE.

APART FROM SKIING, THE LIDO WAS ALSO THE SCENE OF ICE-HOCKEY, SLEDGING AND ICE-SKATING.
