Kenneth Clarke - Conservative Government Minister, UK

Stephen Sackur asks veteran Conservative cabinet minister Ken Clarke if prime minster David Cameron is in danger of losing grip of his party. No one ever said it would be easy for the British prime minister - his government is an uneasy coalition, and his economic inheritance was disfigured by debt. But right now his biggest problems are coming from within. The Conservative Party is fractious; his authority has been challenged on everything from economic policy, to Europe, to his vision of progressive conservatism.
