Iain Duncan Smith

Kenneth Clarke

Steve Richards: He may be the best man, but Mr Clarke is wrong to stand

Leading article: A simple plan - pick the person who plays best at the box office

Supporters:
Most of his backers come from the right. A small group, which proudly calls itself the "awkward squad" of the Tory backbenches, will bang the drum, led by David Maclean.

Best soundbite:
"After two crushing defeats it is time to make a clean break. The public wants a decent and capable alternative to Labour. It is time for a more honest approach."

X-appeal:
Dashing fresh face who could appeal to party rank and file. Chair of the Public Accounts Committee, with impressive media and policy skills. Another fierce Euro-sceptic

Business interests:
Small fees from lectures and journalism. Presented Channel 4's 'Powerhouse' programme

Can he win?
Self-styled "dark horse" could come up on the rails if Clarke and Ancram fall at the first fence and he squeaks ahead of Duncan Smith. An outside bet, as was John Major.
