How to spot a cheater is an age-old question with no concrete answer. But according to a new survey, a person's profession may provide clues as to whether they will stray.

Conducted by Victoria Milan - a website which aims to match up people seeking an extramarital affair - many users came from relatively specific streams of work.

According to the study, those in the high pressure and highly lucrative field of finance were most likely to cheat.

More specifically, 21 per cent of the women surveyed - meaning they were seeking an extramarital affair - were bankers, brokers or analysts.

The second most represented group were also high fliers, with 15 per cent of participants working as either pilots or flight attendants.

Of those involved, 65 per cent of the professional women admitted to sleeping with a co-worker, but a hefty 85 per cent said it was a practise they wouldn't recommend.

Relationship expert said:

There are several different types of cheaters and infidelity comes in different ways, shapes and forms. The most common of these I've narrowed to three types of cheaters and the tell-tale signs can vary slightly

'Are they a once off cheater? Are they a thrill of the chase, repeat offender? Or perhaps they are an accidental cheater.'
