Nikos Alivizatos

Speaking with Prime Minister Alexis Tsipras at the Maximos Mansion just a few hours after he was named as the government?s candidate for president, former conservative Interior Minister Prokopis Pavlopoulos pledged to contribute his ?humble powers in the struggle to extract the country from the nightmarish crisis.?

Prokopis Pavlopoulos, who was nominated for the Greek presidency on Tuesday, is a high-profile politician whose career has been tainted by controversy.

To Potami on Tuesday nominated Nicos Alivizatos, a professor of constitutional law, as a candidate for Greece's president.

?Everyone has an obligation to contribute to efforts to deal with the unprecedented problems facing the country,? Alivizatos said after accepting the proposal made by the centrist party's leader Stavros Theodorakis.

Investigative journalist Dimitris Psarras and his editor at Efimerida ton Syntakton newspaper, Nikolas Voulelis, were on Tuesday cleared of charges of slander and obtaining personal data without consent.
