|President Goodluck Jonathan|
Jonathan's spokesman Reuben Abati said on Monday that the president signed the bill because it was consistent with the attitudes of most people towards homosexuality in the west African nation.
"I can confirm that the president has signed the bill into law," Abati said, without specifying a date but adding that it happened earlier this month.
"More than 90 percent of Nigerians are opposed to same-sex marriage. So, the law is in line with our cultural and religious beliefs as a people," he added.
"And I think that this law is made for a people and what [the] government has done is consistent with the preference of its environment."
