British number one, Andy Murray, will join a strong field at the Artois Championships in June. As well as Murray, world number two, Rafael Nadal, and Australian Open champion, Novak Djokovic, have entered the Queen's Club event in London. Defending champion, Andy Roddick, the world number six, and Australian Lleyton Hewitt will both be aiming for a record fifth title. The grass-court tournament, which is in its 30th year, begins on 9 June.

Last month the 20-year-old Murray returned to the world's top 10 after his second tournament win of the year at the Open 13 in Marseille. Last year Murray missed the Artois Championships due to a wrist injury.
