RMT union leader, Mick Lynch, raised eyebrows as he told Baroness Chapman "I don't even know who you are" during an interview about the ongoing rail strikes.
The Labour front-bencher winced as she defended herself by adding: "Well...there you go...so don't tell me I'm not working-class or whatever."
But it appeared Lynch wasn't having it as he volleyed back, "I didn't tell you you weren't working-class...I don't even know your name."
He then clarified he didn't know her name because he was in a remote studio and couldn't see anyone on-screen.
