Yakasai elections were rigged in the north in 2015

I think there may be some confusion here.

Yakasai is a Hausa word that means "elders" or "leaders" in some parts of Nigeria. However, I'm not aware of any specific election called "Yakasai elections" that took place in 2015 or any other year.

It's possible that you may be referring to the 2015 Nigerian general elections, which were held on March 28, 2015, for the presidency and on April 11, 2015, for the National Assembly and state governorships. The elections were conducted by the Independent National Electoral Commission (INEC) and were widely reported on by local and international media.

While there were some allegations of electoral irregularities and violence during the 2015 elections, there is no credible evidence to suggest that the elections were rigged in the north or any other region. The elections were monitored by local and international observers, including the European Union, the United States, and the African Union, among others.

It's important to note that elections are complex processes that involve many stakeholders, and it's not uncommon for there to be disputes and controversies surrounding the outcome of elections. However, in the case of the 2015 Nigerian general elections, the results were widely accepted by the majority of Nigerians and the international community.

If you have any specific information or evidence regarding alleged electoral irregularities in the north or any other region during the 2015 elections, I would be happy to help you investigate further.
