Iain Macleod was a British Conservative politician who served as Colonial Secretary from 1959 until 1961, and Chancellor of the Exchequer for just one month in 1970, before his sudden death. Widely regarded as the cleverest Tory of his generation, questions remain as to whether he might have kept the troubled Heath government on course, had he lived. 

My guest for this conversation is former Conservative Party leader Michael Howard, who led the Tories into the 2005 general election against Tony Blair's Labour.
