Menna Fitzpatrick and guide Jen Kehoe won gold in the women's visually-impaired slalom at the Winter Paralympics in Pyeongchang, Great Britain's first of the Games.
The pair had already taken two silvers and a bronze but completed their biggest victory by beating Slovakia's Henrieta Farkasova and Natalia Subrtova by 0.66 seconds.
It is only GB's second ever gold medal in the Winter Paralympics.
The medal has taken the ParalympicsGB team to their UK Sport target of six to 12 medals, with the ambition of seven.
Millie Knight and Brett Wild won bronze for GB in the slalom to add to their two silvers in the downhill and super-G.
Kelly Gallagher, who won Britain's first Winter Paralympic gold in Sochi four years ago with Charlotte Evans, was sixth with new guide Gary Smith.
