The 26-year-old secures a famous victory to become the first British woman in the Wimbledon singles semi-finals since 1978.
Johanna Konta has beaten Simona Halep to become the first British woman to reach the Wimbledon singles semi-finals in 39 years.
The 26-year-old came from behind to claim a hard-earned 6-7 (2-7) 7-6 (7-5) 6-4 victory over the Romanian in front of a jubilant crowd on Centre Court.
In doing so she has become the first British woman in the Wimbledon singles semi-finals since Virginia Wade in 1978.
Konta will face five-time Wimbledon champion Venus Williams on Thursday in a bid to reach her first Grand Slam final.
In a gripping contest, Halep looked dominant early on as she stormed into a 4-1 lead in the first set.
The tide appeared to turn as Konta broke back with a backhand winner, but Halep held on and claimed the set in a tie-break.
While 4-3 up in the second set, Konta wasted two break points as she hit a return into the net and blasted another one long.
However, the Australian-born Briton battled back from 3-1 down in a tie-break to snatch the set and keep her hopes alive.
Virginia Wade watched on from the Royal Box as Konta went on to save a break point and then break serve in the following game, earning her a 3-2 lead in the final set.
She held her nerve to serve out the set and secure a famous victory.
Describing how she overcame world number two Halep, Konta said she stuck to her “true self”.
“I knew against Simona she wasn’t going to give me much for free and I had to create my own chances and I took a few of them,” she told the BBC.
“I felt consistent in my approach and in my general being out there. I continued to trust in myself.”
On facing 37-year-old Williams, Konta said: “Age is not a factor.
“She’s a tremendous champion and I feel very humbled to share a court with her again.”
If she had beaten Konta, Halep would have leapfrogged Angelique Kerber to become the world number one.
With her quarter-final win Konta will enter the world’s top five for the first time.
Andy Murray will fight to join Konta in the semi-finals when he faces American Sam Querrey on Wednesday.
