Bromley, Merton and Wandsworth are three of the most promiscious boroughs in London, according to new figures.

More than 5,000 adulterous men and women living in London's 33 boroughs were polled by website xxpanded.co.uk between January and September this year.

The three boroughs made the top 10 adulterous areas in London, with Croydon and Kingston making the top 20.

Kensington and Chelsea topped the list with 12.1 per cent of those in the borough having cheated on their partners.

Lewisham, Sutton, Bexley, Richmond and Greenwich were the most monogamous boroughs of the bunch.

A spokeswoman for the website said that "rich and powerful men and women are likely to cheat" as they have a "heightened ego and a more positive sense of self".
