Jeremy Clarkson has been accused of "fabricating" the danger he was in during his recent trip to Argentina.
The crew had to leave the country after a Porsche with a number plate which appeared to reference the Falklands War angered locals.
It was reported they feared they were going to be stoned to death.
But Argentina's UK ambassador Alicia Castro claimed Clarkson had "fabricated an exaggerated story".
Top Gear presenter Jeremy Clarkson has arrived back in the UK, insisting that his team had not deliberately provoked Argentinians with a numberplate allegedly referencing the Falklands war.
He said his team had been chased to the border with Chile by thousands of people and claimed "someone could have been killed".
He dismissed the idea that the cast had upset veterans of the Falklands, tweeting that those who were upset were not old enough to have taken part.
Footage appears to show the moment protesters throw stones and hurl abuse at the presenters of Top Gear for "mocking" the Falklands War.
