Coventry City Council leader George Duggins has accused Sisu of risking the security of Coventry City Football Club.
Speaking to the BBC's Simon Gilbert, Cllr Duggins said: “Clearly there had just been a four year lease agreed on a two plus two agreement because it was anticipated that the football club would build a new ground and that hadn’t changed.
“What I would say is that the people who are risking the security of the football club are Sisu themselves and nobody else.
“I have been a lifelong supporter of the football club but at the same time I can no longer allow us to rack up the kind of legal costs that we have and I have been calling for it to stop for a long time and I am not going to change that stance because of the fact that the football club and Sisu have got themselves into this dreadful situation that they allowed and got themselves into.”
