Organisers of the 2012 London Olympic Games have pledged that efforts to protect competitors from the local population will not overshadow the month-long festival of sport.
According to sources, concerns have been discretely raised by several countries, in particular America, about their athletes having contact with residents of London or as they are commonly known, 'Cockneys'.
The London Organising Committee has said that despite a 'ring of steel' being erected around the games and those participating, impact on the event will be minimal.
The American government was said to have been particularly concerned about their athletes being tricked out of pound coins by fraudulent tour guides or being served real ale when what they really want is lager.
But Head of the Organising Committee Sebastian Coe has promised that any contact between international athletes and locals will range from "limited to zilch".
Lord Coe said: "Well really it's a whole humph about nothing - plenty of people come to this city ever year and never actually speak to a single native Londoner.
"I've lived here for years and I've only met a handful of these so-called Cockneys in all that time."
To help ease fears, though, Lord Coe said the organising committee has been working with other big cities on initiatives to limit contact with locals.
"I'm happy to announce," he continued, "that after several months of working with officials in New York, 95 per cent of all London taxi drivers are now foreigners and 65 per cent are from one of those countries where they don't mind working 72 hour shifts and they spend all their time speaking on their mobile phones instead of passengers.
"We've also run a special project with bar owners to replace any London-born bar staff with Eastern European workers.
"They're much easier to understand than those speaking the local dialect."
And, in a move that has been welcomed by participating nations, the government has approved new powers for the police which will allow them to adopt a 'shoot on site' policy if they feel there is a "significant risk" of contact between Cockneys and athletes.
However, further fears have been raised over Olympic events to be held out-with London.
Ken Biggles from the Olympic Supporters' Forum commented: "It's looking like athletes will be well protected from locals in London but what about when events are held in Scotland?
"And that's not to mention the risk of exposure in Manchester - what sort of measures will be in place there?"
