Preliminary vote tallies from Mexico's first judicial elections indicate the ruling Morena party is headed toward control over the Supreme Court.

The Morena party controls most of Mexico’s government. Its sway over the Supreme Court is set to increase after a judicial election that raised fears about democracy.

Turnout for Sunday's judicial election was likely between 12.57% and 13.32%, Mexico's INE electoral authority said on Monday, adding that thousands of officials across the country are working to verify the votes cast by citizens.
