Republican presidential hopefuls have taken part in a televised debate in the US state of Iowa.

During the debate, candidate Mitt Romney challenged Texas Governor Rick Perry to a $10,000 bet over what Mr Romney had written in his book.

Some say the size of the bet may give the impression he is out of touch with the public, especially at such a time of economic hardship.
