One in five Brits had sex at work

 One in five Brits has had sex at work, according to a survey which brings a whole new meaning to the term "job satisfaction".

The ICM poll commissioned by The Observer, of more than 1,000 UK adults, went several steps further in demolishing the image of the traditional repressed Brit.

It found that one in five people did not believe that monogamy was desirable, while three out of 10 did not even think it was natural.
