This photo was taken last night by Labour supporter Robert Crego.
He told BuzzFeed he got on the Northern line at Leicester Square only to find himself in a carriage with former Labour leader Ed Miliband.
"'That's definitely Ed Miliband', I thought. Basically I tried to get a photo and the one that I got was him looking directly at the camera," he said.
The 25-year-old, a clinical researcher at a cancer charity, said he felt "voyeuristic" taking the photo.
"But it was just a bit of fun, and I think he thought it was just a bit of fun too."
As if to prove the point, he took another photo of Miliband immediately afterwards, where he looks a tiny bit more relaxed.
