If UKIP break 6% at the next election I'll streak naked down Whitehall in a Nigel Farage mask whilst singing Land of Hope and Glory...— Dan Hodges (@DPJHodges) December 15, 2012
"If Ukip break 6% I'll streak down Whitehall," he tweeted in 2012 and today he honoured that vow after Nigel Farage's party mustered over 12%.
True to his word, clad only in trainers and a pair of black underpants, Hodges completed the run in just 3:37 minutes - defying odds that he might get arrested along the way.
Arriving outside the Houses of Parliament, he said: "I actually feel invigorated, more people should consider naked running."
"Perhaps next time we can turn it into a mass charity flash streak."
The Terrence Higgins Trust lends support to people with, or who are at risk of contracting, HIV.
Sonya Trivedy, its executive director of fundraising, said after Hodges completed Thursday morning's feat: "It is all in good fun but, for Terrence Higgins Trust, Dan's choice to donate underpins a serious issue.
"Ukip leader Nigel Farage's comments before the election, that migrants living with HIV should be blocked from entering the UK, showed an outrageous lack of understanding of the issue, and were based on absolute fiction.
"So Dan's choice of a shared donation to Terrence Higgins Trust because of these outrageous and dangerous claims means a lot."
