Sue Barker hosts coverage as the AEGON Championships at Queen's Club, London, get under way. As always, there will be a world-class field taking part, with players not only hoping to win this prestigious title but also anxious to get a feel for the grass surface ahead of Wimbledon. Rafael Nadal made an impressively swift transition from clay to grass last year, coming to London straight from winning the French Open to triumph at Queen's - it was his first grasscourt title and he landed another at Wimbledon weeks later. Commentators are Andrew Castle, Mark Petchey, John Lloyd and Pat Cash.
