London 2012 courts ruling bodies

London is up against New York, Paris, Madrid and Moscow

London Olympic bid leaders are offering a series of incentives to sports organisations should they win the right to stage the 2012 Games.

Leaders of various international federations and Olympic bodies are in Berlin for the Sport Accord Conference.

And London 2012 announced it would provide free accommodation and expenses for delegates from sports organisations in the year before the 2012 Games.

In addition, a hockey facility is to be built in the proposed Olympic Park.

It was also announced that a new deal struck with the BBC would give a range of sports the opportunity to be showcased globally.

London 2012 communications director Mike Lee said: "These are commitments to the national Olympic committees (NOCs) and to the athletes that we are announcing in three charters about what we will provide.

This race proves that no-one does it better than London, and I hope that the IOC takes note London Marathon winner Paula Radcliffe

"For example, for technical delegates from international federations and NOCs, in the year before the Games we will provide a year's free accommodation and expenses to help them plan and organise.

"These are incentives but they are also practical and helpful measures which will aid the organisation of the Games."

Lee added: "This hockey facility will be built whether the bid is successful or not in the Olympic Park area, though the scope and size depends on whether we win."

Meanwhile, Sunday's women's London Marathon winner Paula Radcliffe used her victory to push the city's claims.

Radcliffe said: "This race proves that no-one does it better than London, and I hope that the IOC takes note."

London was not the only bidding city to offer incentives in Berlin.

New York promised to make "the world's best marketing expertise" available to the International Sporting Federation to promote their own individual sports.

All the bidding cities have been attempting to drum up support among the gathering of several hundred conference delegates.
