However, the ex-Prime Minister’s speech had reinforced her support for Brexit instead of leading her to rally against it.
Speaking to LBC’s Iain Dale, she said: "Directly after voting to leave I was listening to LBC and watching the media like everybody else does. And I felt like what I was talking about, having buyer's remorse.
"I felt a terrible amount of shame and guilt and I thought my goodness, what have I done? You know, I've got this all wrong, there's something wrong with me."
