Members of Nigeria's largest opposition party have agreed to help form a unity government with the ruling People's Democratic Party.
In a statement Wednesday, a faction of the opposition Nigeria People's Party (ANPP) led by a group of regional governors said it has agreed to work with the ruling party to help solve the nation's problems.
The party's presidential candidate General Mohammadu Buhari and some of his allies refrained from signing the agreement.
President Umaru Yar'Adua and his ruling party have held similar talks with at least two other opposition parties.
Mr. Yar'Adua is pushing for a unity government in an effort to unite the nation after highly controversial elections earlier this year.
International observers as well as opposition groups have said the April elections were so deeply flawed as not to be credible.
At his inauguration last month, President Yar'Adua acknowledged there were "lapses and shortcomings" in the elections and promised to address the controversy.
