Asked whether he sat down to watch the Queen’s annual message, he said: “It’s on in the morning, usually we have it on.”
But he was corrected by Etchingham, who told him: “It’s not on in the morning. It’s at three o’clock in the afternoon.”
Corbyn replied by saying he and his family “don’t watch television very much on Christmas Day” and are often out visiting homeless shelters instead.
Pressed on whether he usually watches the monarch’s public addresses, the 70-year-old said: “There is lots to do. I enjoy the presence of my family and friends around Christmas. Obviously, like everybody else does.
“And, I also visit the homeless shelter, either on Christmas Day, or the day before, to talk to, and listen to people’s lives, about how they could be made better with a government that cared for them.”
The full programme – The Leader Interviews: Jeremy Corbyn – Tonight – will air on ITV at 7.30pm on Thursday.
