The conclusion to day 11's action from the grass courts of SW19, where the men's semi-finals take pride of place. Britain has had a competitor to cheer on at this stage for four of the last six tournaments, although a semi-final win for Tim Henman would mark his best-ever performance here.

Meanwhile, the doubles and the mixed doubles will also be approaching their climaxes. This time last year, the latter were sparking more interest than usual with the ongoing success of Leander Paes and his partner, nine-times ladies' champion Martina Navratilova. On this occasion they overcame the challenge of US pair
Mike Bryan and Lisa Raymond 5-7, 7-6 (7-3), 6-4 to reach the semi-finals. Introduced by Sue Barker.
