The trial begins later of a swimmer accused of disrupting this year's boat race by swimming in the River Thames. Trenton Oldfield has pleaded not guilty to a charge of causing a public nuisance.
The race was stopped on 7th April when the Oxford and Cambridge boats were side by side near Chiswick Eyot, London. It was the first time in history the boat race was disrupted by a swimmer. The race was restarted nearly half an hour later. Cambridge went on to win after Oxford broke an oar.
