Sir Peter O'Sullevan in hospital but "perky" after mild stroke The long-serving BBC commentator, who called 50 Grand Nationals, former journalist and successful racehorse owner, is due to undergo further tests over the next couple of days. O'Sullevan, 95, attended all four days of the Cheltenham Festival earlier this month and runs a charitable trust, which has raised millions of pounds for animal and racing related charities. He has complained of blurred vision but is said to be "very perky." A number of close friends have visited him including Mike Dillon, the PR director of Ladbrokes, who saw him on Tuesday and said: "He's been for a walk round with the physio. He's very lucid and seems fine, Nigel Payne, who runs O'Sullevan's charitable trust, said: "Sir Peter is obviously a bit down, but he is in very good hands and everything is being done for him. I don't think it is over-serious, but at the same time when anybody of that age has a stroke it has to be a concern.
