Sprinter Jonnie Peacock has successfully defended his T44 100 metres title bringing Great Britain's gold medal tally to 12 at the end of day two of the Rio Games.

Peacock, who hushed the partisan London 2012 crowd before storming to a memorable gold, made a fine start and triumphed in 10.81 seconds, equalling the Paralympic record he set in Thursday's heat.

Liam Malone of New Zealand came second at 11.02 seconds and Felix Streng of Germany third in 11.03.

Another golden day for ParalympicsGB began in the velodrome with Sophie Thornhill and her pilot Helen Scott winning the B one-kilometre time-trial, while Jody Cundy added a cathartic win in the C4/C5 event, four years after his explosive reaction to being denied at London 2012.

Moments later Georgina Hermitage won the T37 100m final at the Olympic Stadium.

And in the next final Sophie Hahn claimed victory in the T38 100m final.

Britain's 10th gold soon followed in the swimming pool as 15-year-old Ellie Robinson won the S6 50m butterfly.

And Libby Clegg, with her guide Chris Clark, brushed aside a disqualification and subsequent reinstatement to win the T11 100m.

Clegg, in her third third Paralympics, claimed her third medal after silvers in the T12 class at Beijing 2008 and London 2012, with victory in 11.96secs.

The 26-year-old partially sighted runner beat the T11 100 metres world record previously held by Brazil's Terezinha Guilhermina in Friday morning's semi-final, but then a rival lodged a protest.

Britain successfully appealed against the claim that guide Chris Clark had dragged her in the race, contrary to regulations.

It meant the 11.91 seconds world record stood and Clegg and Clark could run in the final.
