Opening up about his setback, Kate revealed that Derek had to be taken to hospital after his kidneys became infected, resulting in him spending time in intensive care.
Detailing the ordeal, Kate told co-host Richard Madeley: "We called an ambulance, went to A&E and they said he had very severe sepsis, life-threatening sepsis.

"So it was really dramatic. Brilliant work by the A&E, absolutely extraordinary, because when you've got sepsis, the big challenge is to find the source of infection quickly, and get the right antibiotics and his blood pressure was so low."
After Richard asked if the doctors found the source of the infection, Kate explained that by the process of elimination, they discovered that it was a problem with his kidneys.
She said: "And unfortunately his kidneys were really badly infected, blocked, and the challenge now is to save them, so that's where we've been for the last three weeks, got the sepsis under control."
Kate continued that Derek is now out of intensive care, but still in hospital.
