The economic benefits of hosting the Olympics have already outweighed the costs it was claimed today.
The Queen hosted a garden party at Buckingham Palace for many of the stars of the London 2012 Games, as well as some other familiar faces.
Thousands of bargain-hunting Olympics fans scrambled for items at a London 2012 sale billed as the "last chance" to own part of the Games.
American sprinter Tyson Gay has been suspended for one year after a positive drugs test, the US Anti-Doping Agency said.
Gay, 31, has had to return a silver medal won in the 4x100m relay at the 2012 Olympics in London.
Post mortem examinations revealed the cause of death of the man as suspension caused by hanging. Compression of the neck was the cause of death for the woman.
While formal identification is awaited, officers said they were confident of the identities of both people.
The man is known as Sanjeev Kumar, 36, also known as Satbir Singh; the woman is called Poonam, 35. Poonam's family have informed officers that she does not have a family name.
Metropolitan Police said their next of kin have been informed.
The Met police said at this stage, officers are treating the death of the woman in Southwall, West London as murder. The death of the man is not being treated as suspicious.
Officers from the Homicide and Major Crime Command are investigating and no one else is being sought in connection with this incident at this time.
Police have launched an investigation after the bodies of a woman and her husband were found at an address in Southall.
Officers were called at around 3.10pm on Friday, 29 November to an address in Priory Way, Western Road, Southall following concerns for the welfare of residents there.
Police attended and discovered the bodies of a man and a woman, both aged in their 30s. Both were pronounced dead at the scene, Met Police said.
The successful staging of the London 2012 Olympics has led to other countries turning to Britain to help deliver their own events, according to a government official.
Reacting to news that the UK had met its four-year target of raising £11 billion worth of economic benefit from the Games in 12 months, Trade and Investment Minister Lord Green said:
"The delivery of London 2012 on time and on budget led to hosting nations turning to the UK to help deliver their own events with supply opportunities running into the billions.
"UK Trade & Investment has played a key role in helping British companies maximise these opportunities and the result is a £11.06 billion boost to the UK economy from the Games, reaching our four-year target in just over a year."
A four-year target of raising £11 billion worth of economic benefit from the London Olympics has been met in 12 months, the Government has announced.
The country has benefited from new foreign investment, additional sales and firms winning contracts since last summer's events, according to a report.
The total includes £130 million of contracts won by UK companies for next year's soccer World Cup in Brazil, and the next Olympic Games, in Rio in 2016.
Boris Johnson reminded Tory conference delegates of his prediction that last year's London Olympics and Paralympics would spur a baby boom.
He told the Conservative Party conference: "I prophesied that the athletes had moved the people of this country to such paroxysms of excitement on the sofas of Britain that they had not only inspired a generation, but probably helped to create one as well."
"Like all my predictions and promises, I have delivered, in that GLA demographics say live births in London will be 136,942, which is more than in any year since 1966 when England won the World Cup."
Despite the beaming smiles of gold medal winners at London 2012, a study at last year's Games has found "high levels" of bad teeth among competing athletes.
Using data from 278 athletes from 25 sports, researchers found 55% had tooth decay or cavities, 45% had dental erosion and 76% had gingivitis. More than 40% were "bothered" by their oral health.
The study, published in the British Journal of Sports Medicine, concluded: "The oral health of athletes attending the dental clinic of the London 2012 Games was poor with a resulting substantial negative impact on well-being, training and performance."
Danny Boyle has said everyone who was part of the London 2012 opening ceremony was "honoured" to work with the "wonderful" stuntman Mark Sutton.
The event's creative director said Mr Sutton had formed "a brilliant partnership with Gary Connery" to make crowd inside "the (Olympic Stadium) gasp" and leave them with "indelible memories" in parachuting in as James Bond and the Queen.
Mr Boyle also paid joking tribute to Mr Sutton for helping to smuggle in treats for the Olympic team in the hard slog towards planning the global show, saying:
Courtesy of loading the helicopter in Essex, and thereby avoiding the official security ban on alcohol in the park during rehearsal, he and Gary also smuggled with them an excellent bottle of wine for the crew each evening and before we all went home we would often drink their health.
They of course, as top stuntmen, never touched a drop but they sensed our need of occasional fortification!
Friends and work colleagues have paid tribute to Olympic stuntman Mark Sutton.
Jackie Harper, a friend and fellow member of the Army Parachute Association at its skydive base in Netheravon in Wiltshire, said:
Mark was an expert wingsuit pilot, very highly regarded by everyone here at Netheravon. He was very generous with his time and giving help and advice to others.
We are devastated and send our condolences to his family and friends. We are really going to miss him.
RBS, where Mr Sutton worked as a contractor in the Markets division, offered "condolences to his family" and said everyone at the bank's "thoughts are with them at this very difficult time".
