England’s women powered into the World Cup final after seeing off Ireland 40-7 at Stade Jean Bouin in Paris.
Katy Mclean’s team produced their best performance of the tournament against opponents whose semi-final appearance had been underpinned by a stunning pool stage victory over competition heavyweights New Zealand.
England will meet France or Canada in next Sunday’s final.
Ireland took the lead through an early try from wing Alison Miller that full-back Niamh Briggs converted, but England established a firm grip on proceedings by scoring 18 points in 13 first-half minutes.
England enjoyed superiority in every key area, particularly up-front, and possessed the game’s outstanding individual performers in Scarratt, her midfield partner Rachel Burford and flanker Maggie Alphonsi and they won easy.
