UK ready for Olympics: Cameron

London: British Prime Minister David Cameron has said Britain is ready for the "greatest show on Earth" as the final countdown to the start of the 2012 London Olympics has begun.

Cameron said the country must show the world "the best of Britain" over the next two weeks after describing previews of Friday night`s 27 million pounds Opening Ceremony as "spine-tingling".

Cameron`s comments were backed up by Culture Secretary Jeremy Hunt, who insisted that preparations were going "very smoothly".

"It`s very exciting," Cameron told BBC News in a televised interview. "I think there is a huge sense of excitement and anticipation, because Britain is ready to welcome the greatest show on Earth. It`s going to be an incredible few weeks for our country. I think it`s a great opportunity to show the world the best of Britain, a country that`s got an incredibly rich past, but actually a very exciting and vibrant future."
