Team GB today announced a 77-member athletics squad which features controversial sprinter Dwain Chambers, as well as young hopeful Adam Gemili.
It signals a remarkable comeback from Chambers, who was famously banned following doping offenses, and sees a huge coup for 18 year-old Gemili who took the UK trials by storm.
There are a number of surprise selections for Team GB, with Lynsey Sharp being selected for the 800 metres following her silver medal at the European Championships last week.
Sharp did not reach the 'A' standard qualifying time, but her 'B' standard was deemed enough by Team GB head coach Charles Van Commenee.
Her inclusion means heartbreak for former world bronze medalist Jenny Meadows, who misses out, as does Marilyn Okoro.
There is also disappointment for 100 metre sprinter Harry Aikines-Aryeetey, whose fourth place in the European Championships final ended his Olympic dream, and hurdler Will Sharman, who missed out to Andy Turner in selection.
Gold medal hopeful Philips Idowu will be attending his fourth Olympic Games, and Olympic poster-girl Jessica Ennis will be looking for her first Olympic gold medal in the heptathlon.
With just 24 days until the start of the games, the strong squad is a signal of intent from Van Commenee, who is targeting eight athletics medals from Team GB, including one gold.
