Answer:
National Party of Nigeria
Step-by-step explanation:
The first presidential elections in Nigeria were held on the 11th of August in 1979. On that day Shehu Shagari of the National Party of Nigeria was elected to be the president.
Only a month beforehand parliamentary elections were held in Nigeria for the first time as well, and the National Party of Nigeria also took lead then.
Previous the leader of the state, Olusegun Obasanjo, held a ban on political parties when the government made changes to the constitution. Only around 40% of voters practiced their voting rights, and there were doubts about who won. In the end, it was proclaimed that Shagari and the National Party of Nigeria shall take the office and start the Second Nigerian Republic.
