Earlier today, when asked about US Republican presidential candidate Mitt Romney's comments questioning Britain's readiness to host the Olympics, Mr Cameron said:
"We are holding an Olympic Games in one of the busiest, most active, bustling cities anywhere in the world.
"Of course it's easier if you hold an Olympic Games in the middle of nowhere."
Some observers thought the PM may be drawing a pointed contrast with Mr Romney's experience as chief executive of the Salt Lake City Winter Olympics in 2002.
In response, Art Raymond, a spokesman for Salt Lake City Mayor Ralph Becker said:
Prime Minister Cameron's comments likely reflect his lack of familiarity with Salt Lake City.
We'd welcome the opportunity to share all that we enjoy here with the PM, including a great number of assets that you'd be hard-pressed to find in London.
We also hosted the most successful Olympic Winter Games, ever.
He can stop by, any time…we'd love to have him and happy to send a map so he doesn't run into any trouble locating the middle of nowhere."
