Gary Hoffman has said that the straw that broke the camels back for him was the loan of Conor Thomas to Liverpool.
Speaking to the CT, Mr Hoffman said: “The specifics should remain confidential, but everyone knows that the catalyst was the loan of Conor Thomas to Liverpool.
“In reality, I should have probably resigned at the beginning of last year like Mike Parton – another serious businessman – but I wanted to stay to help Ray Ranson and stabilise things.
“Everyone can guess that I did not have a great relationship with Sisu. That was because the board was often misled and given inaccurate information.
"Sisu only gave us month by month and week by week promises rather than a plan for the year or three years that would have enabled Ray and the management team to do their job.
“I was also concerned by the way in which people were being treated.
"There are lots of good people who were trying to do the right thing that have left the club.”
