A scorned husband wreaked Valentine's Day revenge on his wife by dumping a tractor-load of horse manure into her beloved convertible after discovering she was was cheating on him.

The furious spouse filmed the incident and placed it on YouTube, after finding his partner's profile on a dating website for people looking for love in rural Britain.

He made the discovery after his wife, who he names as Becky Jones, 37, from Lincolnshire, left her email account open on their computer and revealed she was trying to meet men behind his back.

Her profile on Kissinggates.com, a website for single farmers, admitted she has been married for five years but that her husband is 'a complete idiot' and 'completely crazy.'
