Nigeria is holding presidential primary elections this weekend in anticipation of presidential elections to be held in 2023. President Muhammadu Buhari is not allowed to seek office again in 2023 as he is currently serving his second four-year term. Nigeria is not only the continent's most populous country with a population of over 200 million, it is also Africa's largest economy. It has been ravaged by conflict with Islamist militant group Boko Haram and faces a number of other economic, political, security, and social challenges. The stability of Nigeria is paramount to the region and indeed to the world, so this is an election to watch.
