Wimbledon coverage kicked off at midday today, so - in case you don't have the option to gawp at a TV all day, here's a handy synopsis - John Inverdale introduces action and discussion on the opening day's play at the All England Club, looking back at the talking points in the men's and ladies' first-round singles matches in the third Grand Slam event of the year. This year marks the 125th anniversary of the famous tournament and it is fitting that one of the modern greats, defending champion Rafa Nadal, starts proceedings on Centre Court. Nadal is aiming for a third Wimbledon crown this year and few would bet against the formidable top seed.
