Mexico’s ruling party Morena will gain control of the Supreme Court following the country’s first-ever judicial elections, which were marred by low voter turnout and allegations of a power grab.

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.

Around 13% of Mexicans likely turned out to vote in the country's first-ever judicial election, Mexico's INE electoral authority said on Monday, as the government hailed a successful process while analysts said the low turnout could undermine an already controversial reform.
