A six-party opposition alliance has yet to agree their presidential candidate, and Imamoglu has been mooted as a possible leading challenger to run against Erdogan.
'VERY SAD DAY'[1/5] Istanbul Mayor Ekrem Imamoglu and his wife Dilek sit at his office as a Turkish court sentenced Imamoglu, a popular rival of President Tayyip Erdogan, to more than two years in prison and imposed a political ban for insulting public officials, in Istanbul, Turkey, December 14, 2022.
A jail sentence or political ban on Imamoglu would need to be upheld in appeals courts, potentially extending an outcome to the case beyond the elections date.
"The ruling will be final only after the higher court decides whether to uphold the ruling or not.
Under these circumstances, it would be wrong to say that the political ban is in place," Timucin Koprulu, professor of criminal law at Atilim University in Ankara, told Reuters after the ruling.
