IT WAS a linguistic mix up that caught everyone's attention as Tony Abbott declared to a roomful of Liberal faithful this morning that no one can be a "suppository of all wisdom".

The Opposition Leader made the gaffe at a campaign event in the Melbourne electorate of Deakin where he was implicitly criticising Prime Minister Kevin Rudd for running the government as a "one-man band".

Mr Abbott likely meant to say repository, a place for storage, but instead referred to a drug delivery system inserted into the rectum.

"You don't get good decisions from government if all the decisions are simply made by one person," he said.

"No one, however smart, however well educated, however experienced, is the suppository of all wisdom."

The gaffe caused reporters to giggle but Mr Abbot was unfazed, continuing with his speech before the crowd of about 100 people.

Vision of Mr Abbott's mixup is already being shared on social media sites.

He was launching the campaign of Liberal candidate for Deakine, Michael Sukkar.

"We are a united team," he said of the Coalition.

"We're not a one-man band."
