In the recent past there have been sniggering asides and innuendos reported by various media sources, hinting at his sexuality. That should not make one bit of difference if he is or is a good politician, doing his job well.
However, his friendship with Adam Werritty has ultimately cost him his job, and in some ways his good name.
Not only was Mr Werritty present at meetings, when he probably should not have been, it began to be questioned just who was footing the bill for such jaunts?.
UK Prime Minister David Cameron was insistent yesterday that he would not be quick to judge Dr Fox but rather was prepared for internal findings to be revealed before he decoded what, if any, action to take. Dr Fox however, in choosing to resign today, has left many wondering what else could yet be revealed. Is it a case of he knows that more sensational information will be released and that there will be no escape?.
Of course he could simply have decided that enough was enough. The recent furore must have damaged his relationship with his wife and more.
As a senior Tory politician his fall will hit the coalition hard. He has been said to a very competent defence minister. That said the government already have a replacement in mind. Pundits are guessing that Transport Secretary Phillip Hammond will be quickly moved to Defence. For now it's a case of watch this space after all 24 hours is a long time in politics.
