Good Morning Britain's Kate Garraway says her husband Derek Draper is in a "terrible state" after having his life destroyed by catching Covid.

Appearing on Piers Morgan's Life Stories, she says that contracting Covid at the beginning of 2020 has "devastated" him and that he has been affected "from the top of his head to the tip of his toe". Despite returning home, Derek is still unable to fully communicate and has issues with mobility.

"It does feel as though I walked through a fiery furnace or fell down a rabbit hole. The world went dark and still looking for the light at the end of the tunnel, really," Kate says.

"Derek is thought to be the worst affected living Covid patient in the United Kingdom," Piers points out. "He spent 13 months in hospital - the longest stay of anyone who survived the disease. What has Covid done to your husband?"

"It's devastated him," she says. "From the top of his head to the tip of his toe. His digestive system, his liver, his kidneys, his heart, his nervous system. We're pretty sure that the inflammation did pass through the brain. He still can't communicate, he still has issues with mobility. Fundamentally, he's in a terrible state. Look, he's alive, Piers."

Derek spent more than a year in hospital after contracting coronavirus

There is a more hopeful moment in the interview when Piers reveals a conversation he had the night before with Derek, The Mirror reports: "We had a moment last night when I rang you about this interview. Without warning, you said to me, 'Why don't you talk to Derek?' and Derek replied when you said it was me, very loud, clear, 'Hello.' And I said a few things to him and at the end he said 'Thank you'. I was stunned."

"Well, so were we," Kate replies. "The carers that were with me at the time burst into tears. I mean, I don't want to suggest you're a healer Piers but it was a remarkable moment. It's moments like that that make you realise that he is in there. And we've had others - he will turn to me and say, 'I love you.'"

Piers says: "Every time he says something like that, there's that hope coming back at you saying, 'I'm here, I'm alive, keep going'."

In reply, Kate says: "I think you're right and I think I'm going to cry already. He is there! He's fought so hard to stay in this world and I'm not giving up on him ever. He will have moments of clarity and it's like he disappears again."

Piers Morgan's Life Stories airs tonight at 8pm on ITV.
