Lester ´Improving´ After Health Scare Lester Piggott is making good progress from a recent heart problem and is likely to return to Britain 'after the weekend', according to close friend Sir Peter O´Sullevan.Former commentator O´Sullevan has been a firm ally of the legendary jockey for over 50 years and was due to accompany him at Newmarket on Saturday for the inaugural ´Lester Piggott Day´.However, a decision was taken on Wednesday to postpone the event and instead stage it in the autumn, when Piggott will hopefully be well enough to attend.The 71-year-old is still in intensive care in a hospital in Lausanne, Switzerland.'He´s improving and the anxiety has certainly lessened. I think all is pointing to a good recovery,' said O´Sullevan.'I think Maureen (Haggas, Piggott´s daughter) is back by now and Lester is coming back in an air ambulance after the weekend.'The 11-times champion was suffering problems with his health a few months ago and was first admitted to West Suffolk Hospital in Bury St Edmunds after feeling unwell on Christmas Eve on his return from a trip to Hong Kong.He was released five days late(C) PA Sport
