Frank Zimmerman, 60, who was alleged to have targeted the MP on Twitter and in emails, has been charged with improper use of public communications network.
He was arrested in August by Scotland Yard’s elite e-crime squad.
Detectives investigated an allegation from the MP for Corby and East Northamptonshire who claimed threats had been made against her and her three children.
Zimmerman, of Gloucester, will appear before the city’s magistrates court on December 12. The charge carries a maximum six months in jail, a fine of up to £5,000 or both.
A Scotland Yard spokesman said yesterday: “A man arrested over allegations of malicious communications and threats made via email and a social networking site against Louise Mensch MP has been charged.
“Zimmerman was arrested on August 25 after an allegation was received by police via email on August 22,” he added.
