Emma Raducanu's extraordinary US Open triumph on Saturday led to an explosion of joy in Britain, with Queen Elizabeth II leading the celebrations as the 18-year-old qualifier made tennis history in New York.

Raducanu beat 19-year-old Canadian Leylah Fernandez 6-4 6-3 to become Britain's first women's Grand Slam singles champion since Virginia Wade at Wimbledon in 1977, and the first player to win a major after coming through a qualifying tournament.
