The 68-year-old, who has spent 25 years in the position, confirmed the news at a press conference on Friday afternoon.
"We are not going to put the interests of the board before the interests of the club," he told reporters.
"At the moment, we have all decided to leave but we shall not admit that we are being pushed out because we are being thrown out and that, would be no more, no less than a coup d'état.
"Quite possibly, the moment has come for us to go. I'm sure it has. But we want to leave in our own good time – we won't be shoved out. Whoever comes in to take over must have the shareholders' vote and that might seem a formality but it's not."
Depor were relegated from La Liga last season.
