The former Chester Queen's School pupil is determined to improve on her disappointing performance on her Games debut in 2004.

Tweddle, 23, vowed to become the first British woman to win an individual Olympic medal when she competed at Athens four years ago, but could only finish 19th in the individual event.

Beijing will mark her last Olympic appearance and Tweddle, who competed in the bars at Saturday's British Championships despite injury, is playing down her chances second time around.

"I'm really excited and just looking forward to getting there and doing the best job I can," she said.

"The team's been together for a long time now and I definitely feel we can have positive results."

Tweddle won a World Championship gold medal in 2006, becoming the first British gymnast to win a medal at that level – but no Briton has ever reached an Olympic gymnastics final, let alone the podium.

Hannah Whelan and Marissa King will travel to the Far East for their first Olympics and will be joined by Becky Downie, Laura Jones and Rebecca Wing.

British Gymnastics technical director Matthew Greenwood expressed his satisfaction with the team's "strength in depth".

"We are extremely proud of the women's artistic team that has been selected for Beijing," he said.

"The girls will be very well prepared and in a position to once again prove the great strength in depth that we have now established."
