London 2012 team ambassadors to return
Volunteers who helped the public during the London 2012 Olympic Games will return to support other major sporting events, Boris Johnson has announced.
Thousands of Team London Ambassadors helped people find their way around the city during the summer.
The ambassadors will also be drafted in to help tourists during busy holidays.
The scheme began with a pilot at St Pancras International which got under way earlier and will be rolled out to other locations.
'Highlight of summer'
Mr Johnson said he hoped the volunteers would help to cement the city's reputation as the world's capital for international sport and events following London 2012.
He described the ambassadors as "one of the undoubted highlights of the summer".
There will be 175 ambassadors at a National Football League fan rally at Trafalgar Square on Saturday, and for the American football game between the New England Patriots and St Louis Rams at Wembley Stadium on Sunday.
Teams of volunteers will also be at events at locations including the O2 Arena, and during busy periods at Gatwick Airport next year.
More than 2,000 ambassadors have expressed interest in being part of the initial pilots.
