U.K. Conservative Party chairman Grant Shapps was in an all-out denial mode on Wednesday, after a story broke in the Guardian this week claiming he had edited his own Wikipedia page and those of rival politicians.

The British daily reported that Wikipedia had blocked an account that it alleged was being used by Shapps “or someone acting on his behalf.”

“It is the most bonkers story I’ve seen in this election campaign so far,” Shapps told the BBC on Wednesday.

During the interview with the broadcaster, the politician claimed that his diary proved that he was “elsewhere” when the edits by Wiki user Contribsx were made.

He then went on label the accusations that he was tied to Contribsx as a possible “Labour/Guardian smear campaign” ahead of general elections next month.

The chairman was caught editing his Wikipedia page without revealing his identity in 2012, but claims to have learned from the experience.

“It turns out you should never correct your Wikipedia page,” Shapps told the BBC. “And that’s why I’ve never gone near it since.”
