Olubusayo Fasidi, an immigration lawyer in the United States, has testified before the Lagos state election petition tribunal.
Fasidi appeared before the tribunal on Thursday and was led in evidence by Olumide Ayeni, counsel to Gbadebo Rhodes-Vivour, governorship candidate of the Labour Party in the last election.
The immigration lawyer told the tribunal that Obafemi Hamzat, Lagos deputy governor, who is the third respondent, applied for naturalisation of the US as contained in forms 8CFR/337 and N400.
She claimed that Hamzat took an oath of allegiance in the US to renounce his Nigerian citizenship.
