The tories, as a matter of religious faith, see privatised => efficient, whilst being unclear on the difference between 'efficient at creating shareholder value' and 'efficient at serving the public good'. The political mood music, over the last few decades, has meant that the Labour party has repeatedly found itself obliged to say positive things about privatisation, as part of the process of Being Sensible About The Economy (there is a much longer alternative version of this comment!).
The US -- the world temple of capitalism -- seems to be oddly principled (viewed from outside) about keeping certain things such as the postal service, or USGS, as part of the service to the public realm.
The one service probably immune from privatisation is the Health Service. It's only the most frothing-at-the-mouth right-wingers, the provocateurs just one step away from a rabies injection, who'd even admit out loud to a desire to do that. A politician talking about privatising the NHS would I think be pretty much equivalent to a US libertarian politician talking about privatising the armed forces.
