"Your house can be raided by police and you know you've done nothing wrong and nothing happens for a year," Conservative MP Peter Bone told ITV News Political Correspondent Libby Wiener after it was announced that will not face charges over fraud claims.
"In a way it's alright for me as an MP I'm used to having people say nasty things about me but it's very unfair on my wife and children," he added.
A spokesman for Northamptonshire Police said: "We received a complaint about a suspected fraud and had a duty to investigate those claims. By their very nature, fraud investigations are complicated and can take a long time to complete.
"Following our investigations, we submitted a file for consideration to the Crown Prosecution Service and we have now been informed of their decision."
Wellingborough MP Peter Bone has published a detailed account of his "nightmare at the hands of the police" after his home was raided over benefit fraud allegations.
He said he was first made aware of the visit by officers in March last year by a series of "frantic messages" from his wife.
He said: "What was causing the upset was that three police officers had raided our home without any warning."
