Labour spent almost £600 on fancy dress chicken suits during last year's general election campaign, according to new figures released by the Electoral Commission.
The party has a "track record" of using the costumes in its campaigns, says The Independent, after paying someone to wear one and chase London Mayor Boris Johnson down the street in 2012.
However, a breakdown of party spending in the run-up to May's election shows the Conservatives spent the most during the campaign, coming in at £15.5m, compared to Labour's £12m.

Conservative Party strategists have said it was targeting the social media site that enabled them to win key marginal seats.
"We tested everything: display advertising, Google AdWords, Facebook - we found unequivocally that Facebook was the easiest way to reach the people we wanted to reach in the places we wanted to reach them," chief digital strategist Craig Elder told Buzzfeed News.
He added that Twitter mainly appealed to journalists and people already engaged with politics who were unlikely to change their minds.
"Last time [2010], everyone talked about how it was the first social-media election," he said. "This time around, it actually was and no one noticed."
