Togo's president has signed a new constitution eliminating presidential elections, his office said late Monday, a move that opponents say will allow him to extend his family's six-decade rule. Civil society groups in the West African nation have called for protests.

Parliament will now choose the president. The new constitution comes days after the election commission on Saturday announced that President Faure Gnassingbe's ruling party had won a majority of parliament seats.

There was a crackdown on civic and media freedoms ahead of the vote. The government banned protests against the proposed new constitution and arrested opposition figures. The electoral commission banned the Catholic Church from deploying election observers. Togo's media regulator suspended the accreditation process for foreign journalists.

The new constitution also increases presidential terms from five to six years and introduces a single-term limit. But the nearly 20 years that Gnassingbe has served in office would not count, and the political opposition, religious leaders and civil society say it's likely that Gnassingbe will stay in power when his mandate expires in 2025.
