The act was carried out by environmental campaigner Stan Blackley, who told BuzzFeed News about the memorable balloon-based protest and how Scotland was ahead of the curve compared to the the rest of the world when it came to ridiculing Trump.

"I'd love to say, after 25 years of being a campaigner, that the ballooning was all meticulously planned step-by-step," Blackley said. "But I just found myself behind Donald Trump with a balloon one day and did what any sane and sensible person would have done."

Blackley, who was chief executive of the environmental group Friends of the Earth Scotland at the time, attended Trump's arrival at the Scottish parliament in Edinburgh with a small group of activists who called themselves WIGS – Wind Is Good, Scotland.

For Trump's visit, in which the tycoon was invited to give evidence to a Scottish government renewable energy committee, the group had printed T-shirts and balloons with the slogan "Wind Power Not Wind Bags" placed next to a picture of Trump with his golden hair being disturbed by wind turbines.
