A poll carried out by Opinium for Tideway, the company building the Thames Tideway Tunnel under London to help clean it up, has revealed that 55 per cent of people who live in London think the river, or at least parts of it, is safe enough to swim in.
The survey also found that 45 per cent would be likely to take a dip in the river to cool off in the event of a heatwave. A fifth of the 1,000 people surveyed said they would rather swim in the Thames than a public pool because of the coronavirus pandemic.
