The energy ministry’s Secretary General Apostolos Alexopoulos resigned from his post last Friday for reasons that currently remain unknown, energypress sources have informed.

It is suspected Alexopoulos’s departure may be linked to his diminished role in major energy ministry issues following the re-election of Panos Skourletis at the ministry’s helm.

Alexopoulos, a former Syriza MP, had assumed the energy ministry’s secretary general post immediately following the party’s first election victory, last January.

He served under the then-energy minister Panagiotis Lafazanis, a radical leftist who eventually quit Syriza to form his own anti-eurozone party, Popular Unity, ahead of last month’s snap elections. It failed to reach the three percent electoral threshold in order to be represented in Parliament.
