Senior policy adviser to the prime minister. NEW ENTRY

Until recently Sean Worth was not well known outside a narrow group of politicos but that is likely to change soon. He is the former head of the Conservatives’ policy unit and is widely credited with devising the Tory proposal for a voluntary insurance scheme to fund long term care for the elderly. His brief now covers communication between the DH and Downing Street, something likely to be aided by a good working relationship with Andrew Lansley’s policy adviser, Bill Morgan (32). Politically astute and dedicated to market ideology, Mr Worth will be relied on to push through reform if the DH stumbles.
