Judges aligned with Mexican President Claudia Sheinbaum's ruling Morena political party are expected to dominate the country's Supreme Court after a vote that critics feared would weaken checks and balances on the executive branch's power.

The judicial elections confirmed critics' fears of complete Morena party control within the judiciary — and across all branches of government.

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