The fifth day's play of Britain's major indoor international tennis event at the Empire Pool, Wembley, for £20,000 prize money and the W.D. & H.O. Wills Trophies.
David Vine introduces the highlights of the day's big matches including:
The Semi-Finals of the Men's Singles Championship
This tournament, which counts towards the 1971 final Grand Prix placings, has attracted its strongest ever entry. The field of 32 players includes the holder Rod Laver, American champion Stan Smith, Ken Rosewall, Roger Taylor, Cliff Drysdale, Jan Kodes and a host of international talent.
With the ban on contract professionals looming just over the horizon, it's a unique and final opportunity of seeing all the great players in action in a British tournament - at least for the time being.
