The BBC Radio 2 presenter was pulled from his show this morning, with colleague Vassos Alexander stepping in.
He read out a short statement from Chris revealing that he had left the studio to be with his family.
Vassos told listeners: “Good morning, says Chris.
“The reason I’m not with you today is because just before I came on air my mum passed away and I needed to go straight back home to be with my family.
“But it’s all OK, in fact it’s very much OK, mum needed to be at peace.
“Moreover, she needed to be at peace for some time now, and as she has throughout her life in death she has brought us together.
“She was an incredible woman. Anyone who has ever met her will tell you that ultimately there was no battle lost only a life won. Every single day.”
Vassos added that Chris would return to his presenting duties on Friday morning.
Many of those tuning into the BBC Radio 2 programme this morning revealed that they were in tears as they listened to Chris’ tribute.
The Archbishop of York, John Sentamu, tweeted: “@acrhisevans My dear friend I’m so sorry to hear of the death of your beloved mother Minnie!
