The Good Morning Britain host revealed his ailment when speaking at the Tric Awards in London.
His journey was chronicled in two ITV documentaries, Finding Derek and its devastating sequel, Caring For Derek.
After the former Labour advisor returned to their London home, Kate worked around the clock to bring him back to health.
Kate stated that He was ok in fact, he was back in the hospital, which is a new development. We’ve arrived.”
Derek was diagnosed with coronavirus in March 2020 and spent an agonizing 13 months in hospital, thought to be the longest-suffering Covid sufferer in the UK.
In April of last year, The Sun reported that he had finally gone home to be with Kate and their children.
She said, when asked how her children Darcey, 16, and Billy, 12, have supported her, “They’ve been fantastic – all the way through.”
It took months for Derek to be able to tell his wife that he “loves her” again, a statement he was able to say to Kate for the first time since being ill.
She said in the film that she covertly transported Derek to North America in November for a groundbreaking medical experiment.
