Sir Ian Carruthers is celebrating 40 years of working in the NHS this year, and shows no signs of changing career.

As chief executive of NHS South West, he runs a tight ship - its Darzi vision was notable for the number and preciseness of targets - but has a good track record of working in areas with financial problems. He was acting chief executive of the NHS in 2006 but was thought not to want the top job. But a retirement watching Somerset play cricket - he is a keen sports fan who was once offered a contract playing for Carlisle United - has yet to beckon.
