Ananova:

Cars from Edinburgh and Leeds are the smelliest in the country, according to a new survey.

Car air freshener makers Auto Expressions asked smell expert David Prybus to analyse 130 cars from five cities.

Mr Prybus was asked to rank their smells on a scale from 1 (putrid) to 10 (pleasant).

He found that cars from Slough smelled the sweetest (4 out of 5 cars got more than half marks), while those from Leeds and Edinburgh were the pongiest (more than half got low marks).

Mr Prybus said: "The most common pungent smells came from cigarettes, rotting foods, drinks cans and blankets that lock in pet odours.

"With summer on the way, rising temperatures will make odours more prevalent, so motorists should really consider a thorough spring clean soon."
