TUNIS - Tunisian President Kais Saied has made new changes to electoral law that diminish the role of political parties, three months ahead of legislative elections, in what opposition groups see as the latest step in a sweeping power grab.

A new electoral law published overnight Friday reduces the number of members of the lower house of parliament from 217 to 161, and says candidates will now be elected directly instead of via party lists. Voters will elect a new legislature December 17.

Several opposition parties, including the Islamist movement Ennahdha, have said they will boycott the December elections and say the new electoral law is aimed at muffling them.
