Derek Draper, has been in intensive care for over six months due to complications caused by Covid-19.
On Thursday’s edition of Good Morning Britain, Kate offered an update on Derek’s condition, saying: “The problem is I feel like I’m just boring everyone to death really because it ends up with the same thing, which is stable, but actually in between, when I’m not talking to you, there are big ups and big downs.
“Not big ups, small improvements really and worrying downs as well.
“But the last few days have been pretty stable so keeping everything crossed really.”
Kate said that, due to tight hospital restrictions, the couple’s daughter, Darcey, and Derek’s parents have been unable to see him over the past few months.
“It’s tough, it’s very hard,” she said. “You completely understand why hospitals have to do it.
“They have to protect those inside who may be recovering from Covid or may be dealing with lots of other serious conditions but to do that they have to decrease footfall so Darcy has not been able to see Derek, his mum and dad have not been able to see Derek for a long, long time now.
“The fact that they live in Lancashire and that may go into Tier 2, will have an effect because that will be very tough for them to argue the case to be able to visit if they’re in one of those areas with high cases, so, yeah, it is difficult…”
While Derek, who is a former lobbyist and political adviser, no longer has Covid-19, he still remains seriously ill in an induced coma.
However, he has shown signs of consciousness over the last few months, even occasionally opening his eyes.
Kate recently revealed how Derek had lost eight stone since being admitted to hospital.
The couple, who are both 53, married in 2005 and have a 14-year-old daughter and an 11-year-old son, Darcey and William.
Good Morning Britain airs weekdays at 6am on ITV.
