No, turns out she's the girlfriend of Farage's chief press officer and it was staged
Have a look at the series of pics that were released. The security officer standing right next to Farage doesn't react in any way whatsoever, he clearly knew it was coming
Edit - let's wait and see. The security guy's reaction is questionable as fuck, and Farage is a slimy cocksucker
There were some reports that it was the case because as we all know, all blonde girls are the same person, then it turned out people are just fucking dumb.
Emily Hewertson, a House of Commons press officer, was accused on social media of being the one who threw the milkshake at Farage and has been forced to deny it.
The staffer was contacted by a journalist at the Daily Mail, who asked her to confirm or deny it was her. She posted the message on X (formerly Twitter) with the caption: "No, I did not throw a milkshake over Nigel Farage."
