"The site has grown exponentially, and it's thanks to the turbulent economy and increase in house prices that has left many people financially crippled, unable to divorce should their marriage hit the rocks.
“The good news for those living in Lancashire is that it could be worse. While four towns all appeared in the top 140, none broke the top 10, or even the top 20.
“As for the region’s big city, it, too, failed to post in the upper end of the city index, which means that the citizens of Lancashire can sleep safe in the knowledge that they belong to one of the most faithful counties in the entire country."
