WATCH: Excruciating moment Diane Abbott is forced to LISTEN BACK to car-crash interview
The camera stayed locked on to the shadow home secretary as she awkwardly smiled during the most cringeworthy parts.
At the end of it, Coburn did not let up, as she fired: “That is hugely embarrassing, that’s not just misspeaking to quote you a bit earlier, you just don’t know your figures and you’re not on top of your brief.”
Ms Abbott tried desperately to defend the agonising mistake, saying: “If I didn’t know my figures why was I able to do six other interviews and give the figures correctly.”
She added: “You need to ask why the Conservative Party is so anxious to move the party away from the 20,000 police officers we’ve lost since 2010.”
