Teenager Jade Jones took Great Britain's gold medal tally at London 2012 to 25 by claiming the country's first ever Olympic taekwondo title.

The Welsh 19-year-old beat China's Yuzhuo Hou in the final after beating world number one Tseng Li-Cheng of Chinese Taipei in the semis.

The host nation claimed three golds on Day 13 of the Games.

Charlotte Dujardin won the individual dressage, before Nicola Adams claimed women boxing's first-ever Olympic gold.

With three days of competition still remaining, Britain, who won 19 golds at the 2008 Games in Beijing, have hopes of further success.

Sarah Stevenson will hope to add another taekwondo gold for Britain, while Luke Campbell, Fred Evans, Anthony Ogogo and Anthony Joshua can emulate Adams by becoming Olympic boxing champions.

Sailors Luke Patience and Stuart Bithell are also in with a chance of gold, while Mo Farah will attempt to add the 5,000m title to his 10,000m crown at the Olympic Stadium on Saturday.

Dujardin won GB's first gold of the day, coming out last at Greenwich Park to eclipse the score of Dutch rider Adelinde Cornelissen.

"I wanted to enjoy it, go out and not regret anything," said Dujardin, who also helped Britain to team victory on Tuesday.

Flyweight Adams outclassed three-time world champion Ren Cancan to win her gold.

"It's like a dream come true for me," she said. "I've just wanted this all my life. To think I've finally done it with all this support... it's really made my day."

Jones capped a remarkable day with victory at the ExCeL, eclipsing the bronze won four years ago in Beijing by Stevenson.

"I sang the national anthem and it was the best moments of my whole life," said Jones.

"I've seen this medal on pictures and seen other people get them. To finally have one round my neck, I still don't believe it. It's just crazy."

Britain almost won another taekwondo medal but Martin Stamper missed out on bronze in his weight category.

There was also disappointment for Team GB in the men's hockey competition. Britain were thrashed 9-2 in the semi-finals by the Netherlands and now face Australia in a battle for the bronze.

Ireland claimed their first gold of London 2012 when boxer Katie Taylor, roared on by hundreds of fans, won the lightweight final.

And Kenya's David Rudisha set the first world record of these Games on the track when winning the 800m.

Usain Bolt made history, too, becoming the first man to successfully defend the Olympic 100m and 200m titles.

The Jamaican clocked 19.32 seconds - the joint fourth-fastest time in history - to win the 200m, ahead of countrymen Yohan Blake and Warren Weir.
