Fraser Nelson on Coffee House, The Spectator Blog has this interesting statistic:
The ratio of manager-to-medic in the NHS is one-to-one. That is to say, out of its 1.3m employees (more than the population of some EU member states) just 675,000 are professionally qualified clinical staff. The rest are on the pen pushing/managerial/administrative side of the divide. The average NHS worker takes two weeks off sick every year, in addition to six weeks holiday.
