A man who wore an "I'm with stupid" T-shirt near LNP campaigners during the Queensland election campaign has pleaded not guilty to public nuisance.

Iain Fogerty, of New Farm, was arrested on January 9 after police received complaints that he had inserted himself among campaigners in Brisbane's Fortitude Valley.

More than 10 police officers attended the incident, which happened in the first week of the campaign.

Fogerty, who operated the now-defunct Not Campbell Newman parody account on Twitter, was released on watch-house bail and his matter was briefly mentioned in the Brisbane Magistrates Court on Wednesday.
