Former Vice President Atiku Abubakar on Thursday said Nigeria should learn from the “smooth conduct” of elections in Ghana.

Ghana’s President Nana Akufo-Addo won a second term after a tightly contested presidential election, the country’s electoral commission announced on Wednesday.

“Congratulations to President @NAkufoAddo on his reelection,” Atiku said on Twitter.

“The smooth conduct of the Ghana elections should be an eye-opener to our nation.

“We must undertake far-reaching electoral reforms that address the shortcomings of our previous experiences and strengthens our electoral process.”

Although the Ghanaian election was considered largely peaceful, five people were killed in election-related violence, police said on Wednesday.

The opposition party has also rejected the results and said it will appeal the electoral commission’s decision.
