The host nation had reason to cheer Wednesday as the UK claimed two gold medals. First, rowers Helen Glover and Heather Stanning became the first British women to take Olympic rowing gold.

Then cyclist Bradley Wiggins won the men's individual time trial, the first time someone has won both the Tour de France and the Olympic title in the same year. He has also now won more medals than any other British Olympian.

In gymnastics, Japan's Kohei Uchimura won the men's all-round title. Germany's Marcel Nguyen beat America's Danell Leyva to silver with a stunning floor exercise.

In the swimming pool, Hungary's Daniel Gyurta set a world record to claim surprise gold in the men's 200-metre breaststroke - Michael Jamieson secured a silver for Team GB; America's Nathan Adrian won the 100-metre freestyle by one one-hundredth of a second; and China's Jiao Liuyang won the women's 200-metre butterfly. China also continued to dominate the diving boards, winning gold in men's synchronised springboard.

North Korea's Rim Jong Sim added to her country's medal haul with a striking victory in weightlifting. World table tennis champion Ding Ning of China had to settle for a silver medal when her teammate Li Xiaoxia beat her for the gold medal. And American cyclist Kristin Armstrong won the women's individual time trial.

There was also controversy on Wednesday when eight women's doubles badminton players were disqualified for not playing seriously enough. Officials decided they were trying to lose in order to manipulate the draw for the knockout stage.

At the end of Day 5 China still tops the medals chart with 30 total medals, 17 of them gold. The USA follows with 12 golds. And Korea moves into third place with 6.

Action kicks off in the velodrome on Thursday with the first medals in track cycling. Medals are also up for grabs in women's gymnastics, swimming, rowing, canoeing, table tennis, archery, shooting, judo and fencing.
