Nigel Farage, the self-declared “pantomime villain” of Brexit, is leaving his favorite theater — the European Union’s parliament in Strasbourg — this week with a sense of mission accomplished.

Ridiculed for years, and thriving on the abuse he got from, and dealt to, pro-EU legislators and politicians, he now feels he got the last laugh. On Jan. 31, the U.K. will be leaving the EU, in a historic loss for the bloc — and a historic gain for the likes of Farage.

“When I first came here, I started saying the U.K. would leave the European Union. Everyone thought it was hilarious,” Farage told The Associated Press in an interview, speaking about his early days in the EU legislature in the late 1990s.

The European Union was still thriving, expanding at the time, and could shrug off a loud and sometimes foul-mouthed British parliamentarian as just a nuisance about to be swatted aside by the force of history of closer integration.

Britain may have been a halfhearted member with rumbling about holding onto sovereignty and complaints about “unelected bureaucraats” from Brussels having too much say in their lives. But thoughts of actually leaving? No. Those were left to fringe politicians like Farage.

Conventional wisdom and expert economic studies galore showed that Britain was better in than out, certainly richer. Yet through the hard years, Farage kept on hitting the same nail of national sovereignty and foreign interference.

On top of that, he said in the plenary that then EU Council President Herman Van Rompuy “had the charisma of a damp rag” and sought to get under everyone skin as much as possible.

The former City of London trader had no shame, and now, no regrets.

“I’ve been the pantomime villain. You know what? People stand up and they will boo. And I shall miss that,” Farage said as he faces a deadline to clean out his office by the end of the week.

His fortunes started turning for good on May 29, 2005 when France, ground zero for further EU integration, stunningly rejected plans for a new EU treaty in a referendum.

It was the show of the people’s power he needed. A master at spreading a populist message, sometimes bordering on xenophobic, slowly the signs of the time were starting to move his way.

He said it was a revolution that could never happen from within. Farage quit the Conservative party early on to co-found the U.K. Independence Party in the early 1990s.
