The International Olympic Committee's Evaluation Commission has praised the 'very high quality' of London's bid for the 2012 Olympic Games and Paralympic Games.
The report of the Commission, which has been published just one month before the crucial vote to elect the 2012 Host City, highlights the strong political support for the bid, the legacy the Games would leave in London and the involvement of athletes in every aspect of the bid.
"The bid enjoys strong support and commitment from the Queen, the national government and the GLA (Greater London Authority)," the report states.
"The bid is also supported by all major political parties. This was underlined to the Commission during a meeting with the Prime Minister and the leaders of the two main opposition parties."
The report highlighted the 'significant' sporting and social legacy of London's plans for the East End of the city.
"The Olympic Games would be the catalyst for the regeneration and development of the Lower Lea Valley, site for the Olympic Park," it reads.
"This park would provide significant sports and environmental legacies."
The report also notes that "Athletes have had a direct input into village, venue and operational planning."
London's detailed budget planning, proposals for the Paralympic Games and the consideration of environmental factors were also noted by the report.
"The budgeting process is very detailed and meticulous, and assumptions are well supported and documented," the Commission's summary of London's bid says.
On the Paralympic Games, the report notes: "With its rich history, the capacities of UK Paralympic Sport are among the best in the world."
And the document says that a London Games would have a positive impact on the city's environment.
"There is a strong emphasis on the integration of environmental considerations across all aspects of planning and operations, ensuring minimum impact and maximum sustainability and the integration of those plans and actions into wider regeneration and environmental strategies for London," it says.
"Comprehensive and positive environmental legacies for the community and the Olympic Movement would be achieved from a London 2012 Olympic Games."
The Commission also highlighted the £17bn investment programme already committed to the capital's public transport system.
"During the bid process, substantial London rail transport infrastructure investments have been clearly confirmed, guaranteed and accelerated."
The 13-strong Evaluation Commission visited all five Candidate Cities for the 2012 Games earlier this year, and the 117-page report will be circulated to all IOC members ahead of the 6 July vote.
