The bribes are alleged to have been taken between 2006 and 2014, when mostly conservative administrations were in power. There is also a charge of money laundering, which means the case has to go before the parliament here in Athens which will decide whether to take it to court.
Both former prime ministers and all the accused ministers have issued vehement denials of any wrongdoing. They accuse the leftwing-led government of employing illegal methods for a smear campaign designed to halt the growing lead in the polls of the opposition conservative New Democracy party.

Whatever the truth, Greek commentators believe it could be the start of the biggest sleaze scandal in this country for decades.
