Dee Forbes is resigning as Director General of RTE with immediate effect.
In a statement just issued, she says as Director General she is the person ultimately accountable for what happens within the organisation.
It follows the ongoing controversy surrounding the extra payments given to Ryan Tubridy.
Dee Forbes says she 'apologises unreservedly' for what has happened and her part in the episode.
She adds the RTE Board has not treated her with anything approaching the levels of fairness, equity and respect that anyone should expect as an employee, a colleague or a person.
