Constitution Net has a valuable update on proposals for reforms to the constitution and electoral system of Greece.
Alexis Tsipras and his coalition have proposed
The possibility of direct election and the reinforcement of the competences of the President of the Republic, the proliferation of constitutional referendums, the introduction of the constructive vote of no-confidence, and steps towards the separation of the church and state.
These measures have stalled. However, electoral reform is still advancing.
The SYRIZA-ANEL coalition government did, however, submit a bill on the introduction of proportional representation in Greek election law, which was approved by the Greek parliament on 18 July 2016.
The main change appears to be the elimination of the bonus adjustment. Under the Greek constitution, the law would not take effect at the next election, but only at the one after that. Unless, that is, the government calls a referendum, a path that is apparently inconsistent with constitutional provisions.
