THE call has gone out to find 70,000 “dedicated and passionate” people to help make the London Olympics a triumph.

Organisers last week opened the books of the Games Maker volunteering programme offering enthusiasts “a once-in-a-lifetime opportunity”.

Huge numbers – almost enough to fill the Olympic stadium itself – are needed to act as welcome desk staff, ticket checkers, costume assistants, drivers and event stewards.

Applications for the general roles are now open to those who registered their interest. They have until October 27 to answer the call online at: www.london2012.com/volunteering

Specialist sports, medical, press operations and anti-doping volunteers have been applying since the summer and 8,000 applications have so far come in – close to half of the number needed.

Games supremo Sebastian Coe said volunteering will be challenging. “Games Makers will literally make history happen.”

He added: “Whatever your role, you will help welcome the world and show what the UK has to offer. If you have what it takes to be a London Games Maker, apply now!”

Also on the way is The Young Games Maker programme for up to 1,500 volunteer roles for people under the age of 18. It will be unveiled next July.

Alongside these is London Mayor Boris Johnson’s bid to recruit up to 8,000 “ambassadors” to help and advise the tens of thousands of visitors expected to flock to the capital for “the greatest show on Earth”.

They will be at key points across the city – including transport hubs, outside Games venues, and at popular visitor spots to help the people know where to stay and how to get around the capital.
