Gambia's outgoing president Yahya Jammeh will contest his election loss at before the country's Supreme Court, the ruling party has announced.
Jammeh lost to opposition leader, Adama Barrow - a former Argos security guard - in last week's presidential election.
On Saturday, despite initially conceding defeat to his rival, Jammeh said that he now rejected the poll results "in totality", blaming voting irregularities.
In a state broadcast, the Alliance for Patriotic Reorientation and Construction said it was in the process of filing a petition "against the flawed decision" of the elections commission.
Meanwhile, the President-elect has said the outgoing president has no constitutional authority to reject the election result and order a fresh vote.
"The IEC (Independent Electoral Commission) is the only competent authority to announce the result of the election and declare a win," Barrow said.
The African Union has urged Jammeh to facilitate a "peaceful" transfer of power, and said his rejection of the polls is "null and void" as he already conceded defeat.
