London 2012: Natasha Jonas & Nicola Adams qualify
Natasha Jonas and Nicola Adams have become the first female British boxers to qualify for the Olympic Games after reaching the World Championships semis.
Liverpudlian lightweight Jonas beat Norway's Ingrid Egner 23-9 in the quarter-finals in Qinhuangdao, China.
“I've seen my dad as I was walking round, and he says: 'Yeah, you've done it, you've done it!'”
And Leeds flyweight Adams edged out Indian star Mary Kom Hmangte, 13-11.
British middleweight Savannah Marshall remains one win from qualifying for London, where women's boxing will make its Olympic debut.
Marshall - who beat highly-rated American Claressa Shields on the way to the quarters - defeated China's Jinzi Li 20-8, but must get past Russia's Nadezda Torlopova in the last four to be sure of a place at the Games.
Adams enjoyed a superb win over five-time 48kg world champion world champion Kom to guarantee at least a bronze, with a semi-final to come against Russia's Elena Savelyeva.
The top three Europeans in each weight division in Qinhuangdao qualify for the Games, and Jonas was the first Briton to secure her place - as well as assure herself of at least a world bronze medal.
"It's a great feeling," she told BBC Sport's Leon Mann.
"I've never boxed so many times against such good opponents and it's nice to just come out on top and come here to do what I said I was going to do, and that's qualify.

"But not only did I say that, I said I didn't want to just make up the numbers, I wanted a medal, and that's what I've done.
"I'm absolutely made up that I'm still in it and I'll keep fighting until I get beat."
Asked when she was certain that she had done enough to qualify for London, Jonas said: "I asked one of the coaches.
"We just got it confirmed as we were coming out and I've seen my dad as I was walking round, and he says: 'Yeah, you've done it, you've done it!'
Nicola Adams on the back injury that almost ended her career
“I was laid up without moving for three months. But today all the hard work, the tears and the ups and downs have paid off”
"To know that I'm going to go out in London and there could possibly be 10,000 people cheering for you for a change is just unreal. I can't wait to get on the stage and show them what boxing's all about."
And on the subject of winning a medal in London, Jonas added: "Don't expect nothing less, that's what I'm there for."
Jonas will take on will face Russia's Sofya Ochigava in the semi-final. Ireland's Katie Taylor, going for a fourth consecutive world title, qualified in the same lightweight division as Jonas on Wednesday.
"It's a dream come true, I just can't believe it really," said Taylor. "It's just years and years of hard work really to get here, now I'm going to be an Olympian."
Adams has battled her way back from a back injury that almost ended her career in 2009 and she struggled for funding.
She said: "You can't imagine how happy I am not only to finally reach the Olympic Games but to beat a five-time world champion in order to get there.
"I'm boxing the best people in the world at the moment and I'm still coming out on top. My confidence is going through the roof and I want to go further and win the world title and then the Olympics."
"I was laid up without moving for three months and when I first got back to training I couldn't do one single sit-up. But today all the hard work, the tears and the ups and downs have paid off.
"Not only that but it is brilliant for the team because Natasha has qualified too and Savannah is getting close. We are all focusing on trying to win the world titles and then it will be all about the Olympics."
