Some may have thought there were three centurions at The Oval for Surreyâ..s rout of Gloucestershire. There were actually four. Alongside Phil Weston, Mark Ramprakash and James Benning was Henry Allingham who, at 109 years of age, is the oldest man in Britain. And, fittingly, it is exactly 100 years since Mr Allingham last visited the ground â.. and watched WG Grace play for the Gentlemen against the Players.
