Andy Murray will be hoping for gold glory later on the back of the country's most successful day in modern Olympics history.

The tennis star is certain to win silver or gold when he takes part in two tennis finals - against old rival Roger Federer in the singles and then with Laura Robson in the mixed doubles. It was exactly four weeks ago that Murray lost to Federer in the Wimbledon men's final.

Saturday night saw a golden hat-trick for Britain in the Olympic Stadium when Jessica Ennis, Mo Farah and Greg Rutherford each won their events within 45 minutes of one another.

"Super Saturday" had earlier seen three other gold medals awarded to Team GB athletes - two in rowing and yet another in the velodrome, propelling Britain to third place in the medals chart. The frenzied crowd in the 80,000-capacity stadium went wild as Ennis, the poster girl of the London Games, won the 800m with a sprint finish, crowning two days of tough competition in the heptathlon.

Ennis wept as she stood on the podium to receive her gold medal. She told the BBC: "Obviously having missed the last Olympics in Beijing, I was just trying to make the most of it and enjoy it. But yeah, it was so much pressure, everybody expected me to win and I just knew how hard it was going to be, so I'm just so relieved that I've got the medal now."

Rutherford was the next athlete to claim victory for Team GB, with a surprise gold medal in the long jump. He described his victory as the "most amazing feeling in the world". He was followed by Farah who danced for joy around the track after winning the 10,000m, hailing it as "the best moment of my life".

It topped off a day which also saw success away from the stadium - a sensational world record-breaking performance by women cyclists in the frenzied atmosphere of the velodrome led to another gold in the team pursuit. The team of Dani King, Laura Trott and Joanna Rowsell led from the start to beat the US in a world record time of 3:14.051.

And earlier, at Eton Dorney, an ecstatic crowd cheered the men's coxless four of Andrew Triggs Hodge, Pete Reed, Tom James and Alex Gregory to a victory, which extended Britain's dominance in the event to 16 years. This was followed just minutes later by Kat Copeland and Sophie Hosking claiming gold in the lightweight event.

It was the best day for gold medals since 1908 with Team GB now boasting 14 gold, seven silver and eight bronze and in third place after China and the US. London Games chairman Lord Coe said it was the "the greatest night of British athletics".

Meanwhile, all eyes will be on Louis Smith as he looks to win Great Britain's first ever gymnastics Olympic gold when he competes in the pommel horse final and back in the velodrome, Ed Clancy will battle it out in the men's omnium. And in sailing Ben Ainslie will become the greatest Olympic sailor of all time if he manages to topple Denmark's Jonas Hogh-Christensen in his final race at Weymouth, while Iain Percy and Andrew Simpson are guaranteed at least bronze in the Star class.
