Swimmer Tom Dean struck gold for a second time at the Tokyo Olympics as day five began with more medals for Great Britain. Dean, who won the 200 metres freestyle on Tuesday, returned to the pool as part of Great Britain’s 4x200m freestyle relay team alongside Duncan Scott, James Guy and Matthew Richards, and triumphed again. There were contrasting emotions for Britain’s rowers as a run of five successive Olympic golds in the men’s four came to a disappointing end, but then a silver medal in the quadruple sculls went to Harry Leask, Angus Groom, Tom Barras and Jack Beaumont.
