Super-heavyweight boxer Anthony Joshua has put the seal on a golden Games for Britain as he won a dramatic Olympic title.

His close victory takes Team GB's incredible gold tally to 29 with the possibility of one final medal to come in the modern pentathlon. An ecstatic Joshua, 22, raised his hands in triumph while his cornerman and coach went wild along with the 10,000 crowd in the ExCel.

Another medal was won in the ring on Sunday when 21-year-old Welshman Fred Evans took silver after a brilliant Olympics in which he exceeded expectations. Evans, from Cardiff, said: "I'm only 21 - I'm one of the youngest seniors here - so I've done well and I'm over the moon with getting to the final."

In the modern pentathlon Samantha Murray is third with the last disciplines of riding, and running and shooting still to go.

The Olympics will climax with the closing ceremony later on Sunday, with Games organiser Lord Coe urging the nation to "party, party, party" when the musical extravaganza gets under way.

The handover from London 2012 to the Rio 2016 team will take place along with the extinguishing of the flame, signalling the end of the Games. Traditionally, it is a chance to celebrate what the athletes have achieved and also for a massive party.

The 2012 closing ceremony - called A Symphony Of British Music - will celebrate music as one of Britain's strongest cultural exports over the last 50 years. Many of the 10,000 athletes will be involved and will reportedly file past spectators along the aisles of the arena before gathering around the central stage in their own "mosh pit".

Artistic director Kim Gavin said: "We want it to be the best after-show party there has ever been."

The two-hour, 45-minute grand finale will start with Elgar and Waterloo Sunset at 9pm. Pop stars expected to perform include the Spice Girls, George Michael, the Pet Shop Boys, The Who, Jessie J and Tinie Tempah.

Ben Ainslie, the most successful sailor in Olympic history, will carry the flag for the British team at the ceremony. London 2012 saw the 35-year-old win his fourth consecutive gold to add to the silver he won in his first Olympics as a 19-year-old in Atlanta in 1996.
