LONDON - The London Olympics countdown entered its final 200 days on Monday with government and organisers talking up the legacy Britain can look forward to long after the last medal has been won and the show is over.

On the day three more Games venues had their future ownership announced, Prime Minister David Cameron was due to hold his first cabinet meeting of the New Year at the Olympic Park in Stratford, east London.

"I want the message to go out loud and clear, from tourism to business, sport to investment, we are determined to maximise the benefits of 2012 for the whole country," Cameron said in a statement.

"Today, as we mark 200 days to go, and six out of the eight Olympic venues having already secured their future, we are well on track to delivering a lasting legacy for the whole of Britain."

Sporting legacy and the economic regeneration of a run-down area of east London, without the facilities becoming a drain on public finances after the Games, were central to London's successful bid in 2005 but critics have questioned how much money the government can recoup.

Details on the operators to take over the wave-shaped Aquatics Centre, multi-use Handball Arena and 115 metre high steel AccelorMittal Orbit feature will be announced by the Olympic Park Legacy Company later in the day.

The new contracts will create at least 254 jobs on the Park, whose estate management and maintenance has also been secured, and means six of eight permanent venues now have a clear ownership beyond the Games.

Million Visitors

The government expects the Orbit, a landmark helter-skelter of a structure designed by artist Anish Kapoor and taller than New York's Statue of Liberty, to attract up to a million visitors a year.

They hope the Aquatics Centre could see 800,000 users a year as a local community facility accessible to all as well as remaining a venue for world class events.

The multi-use Arena will become the capital's third largest, hosting up to half a million visitors a year to concerts, exhibitions and sports events.

The remaining two venues yet to have confirmed legacy operators are the main stadium, which has cost 486 million pounds ($748.81 million) to build, and the international broadcast and press centre.

"To find operators to take over these world class facilities so far ahead of the Games and to secure their commitment to spread jobs and opportunities throughout the local communities is the icing on the 2012 cake," said London mayor Boris Johnson.

"We can now start the run in to a fantastic year of celebration with huge pride and optimism that London will stage a great Games, delivering lasting sustainable benefits long after the athletes have departed."

Paul Deighton, chief executive of organising committee LOCOG, urged businesses and the public to embrace the Games and not squander the opportunity of a lifetime.

"The thing that keeps me up at night is whether we will take full advantage of the extraordinary opportunity coming our way this summer," he told the Guardian newspaper.

"I know that by the time we get to the end of this most people will say that they had no idea of the scale and opportunity of this, if only. I don't want too many if onlys."
