Kirkpatrick Macmillan, 69, had a breakdown in June after becoming extremely fearful that the UK would vote to exit the EU.
He could not sleep at night and sought help from a psychiatrist, but promised his GP he ‘would never’ end his life.
But just over a month after the result, his wife found him hanging in their home in Kent.
A report from his psychiatrist, heard in court, said: “In July 2016, Mr Macmillan requested to see me urgently.
“He told me that he had been fine until a month ago.
“He said he was suffering from a totally different breakdown.
“This time he felt unwell and said he was anxious about the Brexit vote.
“He had insomnia and was losing weight due to the anxiety and his concentration was very poor.
“He had no thoughts of self harm, saying it was something he would ‘never do.'”
“He has been described as a person who probably thought a bit too much about others.
“He had suffered from anxiety earlier in his life. He sought help and it seems to have been in good effect.”
“His wife Pauline was confronted by the most terrible discovery. She found him hanging by a scarf around his neck.
“Attempts were made to resuscitate him but he tragically died the following day.
“Due to the evidence about his battle with anxiety and the manner in which he was found, my conclusion is one of suicide.”
