A wildlife expert has issued an appeal to Londoners amid a “sharp increase” in seal sightings in the Thames - which she says is likely to become a “new normal” in the capital.

Mary Tester, founding director of Thames Seal Watch, said there has been a sudden surge in seal sightings in the capital as more of the mammals appear to be making their way up the river and “exploring areas of London”.
