Dutch world champion Dafne Schippers ran a season's best 22.14 but was a distant second to Asher-Smith, who can complete the treble in the 4x100 relay on Sunday.

Jamile Samuel completed the podium after she ran a personal best of 22.37.

“Honestly, I am so stunned,” Asher-Smith told Eurosport.

Normally I am not lost for words but I am just so unbelievably happy.

“I have wanted to get under 22 seconds for a while now so to have done that and win the European champs means so much.”

Asher-Smith, who claimed bronze in the 200m at the Commonwealth Games earlier this year, broke her own British record of 22.07, which has stood since 2015, and has now run world-leading times in both the 100m and 200m events at these championships in Berlin.
