Derek, 53, fell ill in March 2020 after contracting coronavirus and has required a long recovery in intensive care, during which he was placed in a coma.
After more than a year in hospital, he was considered well enough to return to his North London home in April.
Kate has been very open about her husband’s illness and provided a new update on his condition.

Speaking to The Telegraph, she said: “Everyone wants to know how Derek is doing, and I want to say: ‘He’s doing great!’ Because I so want to give them a happy ending…”
She added: “It’s not been easy.
“And although there are these extraordinary little moments that keep you going, it’s not as though there is something every day taking us forward.
“The doctors believe that there will be a trajectory, but that it’ll be very slow. Derek will still sleep for 20 hours a day, for example.”
The Good Morning Britain presenter has kept ITV viewers up to date on her husband’s condition throughout the pandemic.
The former I’m A Celebrity contestant created an award-winning documentary Finding Derek based on her husband’s battle with Covid.
