Who's having outdoor sex?

One in three saucy Britons has had sex in public, a cheeky survey has revealed.

And despite the nippy weather up north, folk in Yorkshire and Humberside - home of the Humber Bridge - are most likely to have a lark in the park.

Amazingly, a whopping 43 per cent of those quizzed didn't even realise activities such as having a romp in public were illegal.

More than 3,000 adults were quizzed by TV channel Alibi.

The results give a fascinating breakdown of which crimes seem to be more acceptable where.

People in the South West are the most likely to make false insurance claims. But Londoners are the least law-abiding citizens.

They top the list for five of the crimes listed below, including doing a runner from taxis and stealing from work.

Steve Hornsey, head of the crime drama channel, said: "Our survey shows that even with the best of intentions, many people cross the line in breaking the law."
