This is my opinion on Charlene's departure that I posted on the I'm a Celeb thread. Only my take on it though.
It seemed to me that Charlene had possibly been called to the Bush telegraph & warned that her decision not to sleep in the RV was going down very badly with the public. Her 'remaining impartial' & 'journalism is my first job' weak excuses were very recent & she repeated those phrases constantly during her exit interview. It sounded like she'd been told what to say by ITV as a PR damage limitation explanation.
Or maybe I'm too suspicious!!
