Sure you are not confusing this:

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."
