Officials from Paris, New York, Moscow, London and Madrid are campaigning to win the support of International Olympic Committee members voting on the 2012 bids on 5 July 2005, in Singapore.

The latest seminars were a rare chance for rivals to make individual presentations and come just a few months after the IOC told the cities which areas of the bids fell short.

With a clear idea of what the IOC wants, cities are using the same key phrases like "athlete-centred", "clustered venues" or "sustainable legacy", and bolstering their bid team with an array of former Olympians.

BBC News Online looks at what else they had to say:

Slogan: "Pride, passion, commitment"

Brought an all-star team to deliver its message including London Mayor Ken Livingstone, Culture Secretary Tessa Jowell, Olympian Sir Steve Redgrave and a video message from Prime Minister Tony Blair.

The Olympics would leave a "lasting legacy" in London, says Blair

In a passionate plea recorded on a visit to the Olympic Village, Mr Blair - in a sleeveless blue sports top - said the Olympics would leave a "lasting legacy" in Britain.

Key improvements to the London bid include a revised transport plan that will see �3bn spent over the next five years.

Bid chairman - and double Olympic champion - Sebastian Coe said work would begin on a new aquatic centre on Monday, at the Olympic Park site in East London.

Britain's passion for sport and the Olympics is a key selling point, he said, as is London's promise to set new standards for sustainable development.

Mayor Livingstone told BBC News Online: "Any of these five cities would put on a good Games. But I think we have made the best of the bids so far - although no one thinks we will have the Games as a right."

Slogan: "L'amour des jeux" (Love of Sport)

Seen by many commentators as the current front-runner, Paris says almost all its infrastructure for the Games already exists.

The Paris team boasts the city's "love of sport"

It boasts an array of world class venues including the Roland Garros tennis stadium and the Stade de France.

It also plans to use the Eiffel Tower as the spectacular location for a range of events like beach volleyball and the start of the marathon.

Eighty percent of sports will be hosted within 10 minutes of the Olympic Village, which will itself be split into two clusters becoming a "new arrondissement" of Paris.

Paris says its bid is the culmination of 20 years of commitment to bringing the Olympics to Paris.

Bid CEO Philippe Baudillon told BBC News Online: "I'm not interested in being the favourite. At the end of the day it's the IOC members, not the media who will decide."

Slogan: No big catchphrase, but banking on its "Olympic X Plan"

The team from New York gave perhaps the slickest presentation, and showed a moving montage of a torch relay through the city, with John Lennon's "Imagine" playing in the background.

It says New York's ability to deliver on security and building work are its key strengths.

Visa concerns dog New York's bid

The X Plan refers to the two intersecting transport routes on which almost all venues will be found - with the Athletes' Village at its heart.

New York's bid team rejects concerns that US visa restrictions will hamper athletes getting to the Games, and says special rules will be in place to ensure Olympians can compete.

It points to the $13bn worth of construction projects completed in the city each year as evidence it will get the job done.

And the city boasts venues like Yankee Stadium, Central Park and Flushing Meadow.

NYC Deputy Mayor Dan Doctoroff told the BBC: "It's still very early in the process. We have 11 months to convince the IOC - I know we can do it."

Slogan: "Imagine it now"

Technical difficulties and an official's broken English marred the presentation, but Moscow points to the "enormous progress" made in the bid since the IOC gave its feedback.

The bid team says it is spending at least $550m to make it the "risk-free" choice for the IOC.

Russian officials say Moscow's river could be used to transport visitors

It says 71% of its venues are already built, and since the 1980 Moscow Olympics it has hosted more than 100 major international sports events.

Moscow puts its river at the heart of its bid. It says more than 60,000 visitors can travel by boat from 70 passenger piers to Olympic venues in what it says is "one of the most compact Games plans ever designed".

Alexander Chernov, bid manager, said: "Russia has gone through unprecedented social, political and economic change in the past decade - we know from the 1980 Games that the Olympics leave a sustainable legacy for a country and its people."

Slogan: "Olympic Passion"

Madrid - like New York and London - says it is a "city of the world" but it has never hosted the Games.

Officials said Madrid has the "most complete public transport system in Europe", with 12 metro lines.

Madrid has never hosted the Games

It plans to concentrate 25 Olympic sports' facilities in three clusters - a watchword of the presentations.

The Olympic Village will be within 20 minutes of these sports.

More than 89% of people in Madrid support the bid, the team said. Some 70% of venues already exist.
