Favourite Sharpe produced some jaw-dropping aerobatics to post a winning score of 95.80 on her second run, celebrated by raising her hands behind her head to give a bunny-ear sign as she crossed the line backwards.

Frenchwoman Marie Martinod matched the silver she earned in Sochi four years ago with a best of 92.60, while Brita Sigourney claimed bronze a further point back after edging out fellow American Annalisa Drew.

Sochi gold medallist Maddie Bowman's hopes of retaining her title were dashed when she suffered a nasty spill on her final run, the American needing medical attention before limping to the finish on one ski in tears.
