Catherine and Michael share two children together; Dylan, 20, and 17-year-old Carys.

Dylan and Carys were both living away from home prior to the coronavirus outbreak, but have made the most of being at home with their parents.

On what has been a highlight, she added: "Just to have the time to be together and to talk, it's been really great. I've really enjoyed having the whole family together."
