Watch: Michael Parkinson branded ‘unrecognisable’ in GMB interview

Sir Michael Parkinson’s appearance on Good Morning Britain on Tuesday surprised some viewers.

The veteran interviewer was on the programme to discuss his new book ‘Like Father, Like Son’ which was inspired by his father's death 40 years ago.

Parkinson, who was joined by his son, wore a grey jumper and was wrapped up in a scarf as he spoke outside via video link from Maidenhead. However, some of those watching at home didn't recognise the star.

"Parky is hardly recognisable there #gmb," remarked one Twitter user, while another added that the 85-year-old "looked frail".

Parkinson spoke about how he had addressed his father's death for his Life Stories interview with Piers Morgan last year, and that it brought up a lot feelings he had about the loss.

"In the end it's bound to come out because it's too potent, it's too much a part of your being," he explained. "That's what the conversation with [Morgan] did, I was fine and we joked about it before, 'You're not going to make me cry'.

"But it did, it opened a door that I had closed for too long, and the memory of [my father] in that bag and being in that bag, reduced to that, my father.
