WADA conducting doping tests at Jerez

McLaren driver Jenson Button arrived late to his scheduled news conference at Jerez on Monday because he had to take an anti-doping test, his first for "about two years" he revealed

"We normally have a doping test once a year - a Wada [World Anti-Doping Agency] test - at home or wherever you are," explained the 35 year old, "But I hadn't had it for a little while."

"Mine was only a [urine] test, some other people had blood tests, I think," added Button.
