William Hague has released a statement after internet rumours caused his special advisor to resign.
Christopher Myers is leaving his post because of "untrue and malicious" allegations made against him.
In a very personal statement the Foreign Secretary has revealed he and his wife Ffion have suffered the pain of multiple miscarriages
The statement said: "Earlier this year a Sunday newspaper began questioning whether my marriage to Ffion was in trouble, and last week another media outlet asked whether there was a statement about our supposed separation. This seemed to be linked to equally untrue speculation surrounding the appointment of Christopher Myers as a Special Adviser."
Mr Hague has addressed speculation surrounding the election campaign trail and how he and Mr Myers occasionally shared twin hotel rooms.
"Neither of us would have done so if we had thought that it in any way meant or implied something else.
"In hindsight I should have given greater consideration to what might have been made of that, but this is in itself no justification for allegations of this kind, which are untrue and deeply distressing to me, to Ffion and to Christopher," he continued.
The Foreign Secretary described how he and his wife felt it necessary to open up and also how they would love to start a family.
"We have encountered many difficulties and suffered multiple miscarriages, and indeed are still grieving for the loss of a pregnancy this summer. We are aware that the stress of infertility can often strain a marriage, but in our case, thankfully, it has only brought us closer together."
"It is very regrettable to have to make this personal statement, but we have often said to each other "if only they knew the truth..."
Well, this is the straightforward truth. I will not be making any further comment on these matters."
