The source added: “Matt Hancock is a horrible individual. He is definitely not a gentleman. He keeps trying to suggest that all is fine when everyone has been left shattered by this. He has been horrible to Martha and has not at any point apologised to her or the rest of the family for what he has done.”

This week, Mr Hancock and Ms Coladangelo, 44, were photographed together for the first time since their affair was made public at a mountain resort in Switzerland. 

There had been speculation that Ms Coladangelo had chosen to stick with her husband, Oliver Tress, the owner of the high street chain Oliver Bonas, with whom she has three children. 

Mr Hancock has been privately briefing that he is in love with Ms Coladangelo, who he had appointed as a non-executive director at the Department of Health and Social Care, and that they remain a couple but living at separate homes. 

The Telegraph has confirmed that Mrs Hancock was unaware of her husband’s infidelity until the expose by the tabloid newspaper. Mr Hancock told his wife their 15-year marriage was over on the evening he learnt that The Sun was about to publish the compromising video footage. 

He refused to quit and Boris Johnson refused to sack him. At the time of the publication, Mr Hancock declined to apologise to his wife but did say sorry for breaking social distancing rules. 

He was forced to quit as health secretary a day later amid intense criticism from backbench Tory MPs and, in his resignation letter said he wanted to “apologise to my family and loved ones for putting them through this. I also need [to] be with my children at this time.”

Mr and Mrs Hancock, a trained osteopath, met at the University of Oxford and were married in 2006.
