Ministers have written to the City of London demanding it stop people from swimming in a protected pond on Hampstead Heath, after disturbing scenes of cygnets and eggs being disrupted went viral on social media.
Swans and their 12-day-old cygnets were disturbed by hordes of splashing revellers in the north London park on Monday as temperatures reached a record 35C in the capital. In one video, a swan was seen poking an unhatched egg with its beak after it fell into the water during the chaos.
