The 200th anniversary of the modern Greek state in 2021 must coincide with a new constitution "by the people and for the people," which ushers in a new political era of democracy and dignity for all Greeks, Prime Minister Alexis Tsipras said on Monday.

"The 24th of July is a milestone for democracy," Prime Minister Alexis Tsipras said in his message for the 42nd anniversary of the post-Junta period and called on all political and social forces to a broad, open and fruitful dialogue on constitutional reform.
