UK entreprenuers work longer hours and pay themselves less than their counterparts who work for other people.

That's according to a report by the Durham Centre for Entrepreneurship, carried out for the Economic and Social Research Centre.

It also found that the number of self-employed businesswomen had stagnated since the early 1990s, and that successful, older entrepreneuers were less likely to retire.

Report author, Professor Simon Parker, said:

"It seems to be:'Why stop while there's a good thing going?' - a very understandable sentiment."
