Giokos was a rising star within the organisation having joined eNCA from CNBC Africa in 2011.
However she will soon be joining Bloomberg TV Africa as an anchor working out of Johannesburg.
"We're very sad Eleni is leaving us. She is a very popular member of the team and a true professional." says Group Head of eNCA, Patrick Conroy.
Giokos was destined to anchor a new business show on eNCA, but opted to join Bloomberg TV Africa after lengthy talks with both channels.
"I'm very torn about my decision. eNCA offered me a tremendous opportunity which sadly I've had to turn down. I had some of my best times as a broadcaster at eNCA. My bosses and my colleagues were always amazingly supportive and great to work with. I learnt so much from Patrick Conroy and working in such a professional environment. And so it is with a heavy heart that I find myself having to say goodbye."
Giokos was an instant on screen success for eNCA anchoring live breaking news events such as the Nairobi terror attacks and the Oscar Pistorius saga in February.
Earlier this year legendary CNN business anchor, Richard Quest, agreed to co-host a show with her on eNCA.
"In the competitive world of 24 hour news your talent is always at risk of being poached. eNCA has become a recruitment ground for international networks and rival 24 hour news channels. We actually take it as a compliment. So it is with mixed feelings that we say goodbye to Eleni. We had hoped she would stay with us, however we are proud that she is held in such high regard by a major international broadcaster." says Conroy.
eNCA will announce her replacement in coming weeks.
