We've got some big national elections coming up in the first half of 2023. In February, voters in Nigeria, Africa's most populous and largest economy, will pick a new president. Three months later, Thais head to the polls in what will be a major test of the army's political power. And in June, Turkey's President Recep Tayyip Erdoğan faces his toughest reelection bid since coming to power in 2014. Here are votes scheduled to take place in the first six months of the year, excluding microstates.
