Shadow Chancellor of the Exchequer Ed Balls has been caught on camera doing a rendition of Psy's Gangnam Style, while dressed in a floral lei of Labour's colours.
The MP for Morley and Outwood appeared to be having a good old knees up at the Labour party conference in Manchester on Monday 22 September, in a video taken by reporter David Churchill.
Balls and his colleagues took time out from outlining the party's 10-year "national mission" to transform Britain, in which leader Ed Miliband pledged to build a "world-class 21st century health and care service" and halve the number of people living on low pay.
The shadow chancellor, meanwhile, promised a more punitive rate of mansion tax for most expensive homes.
But after unveiling the ambitious plans for "Britain 2025" it seems everyone let their hair down for the party.
Balls performed an excellent version of the South Korean musician's hit single dance - and Gangnam Style appears to be a consistently popular choice for British political party conferences.
At the 2012 Conservative party conference, Mayor of London Boris Johnson admitted "Gangnam Style was rather good" – before prevaricating about the vast variety of exports that originate from the capital, including television aerials that the Koreans use to watch the hit video.
He also told the audience he and Prime Minister David Cameron had danced "Gangnam Style" just a few days before the conference, at Chequers Court in Buckinghamshire.
One of the guests remarked: "It was uproarious – Johnson and Cameron completely brought the house down."
