Ivory Coast opposition leader Tidjane Thiam said on Wednesday he would fight on to run in the West African nation's presidential election due in October despite having been removed from the electoral roll.

A lawyer says an Ivory Coast court has ruled that former Credit Suisse CEO Tidjane Thiam is not eligible to run for president because of his dual Ivorian-French nationality.

An Ivory Coast court’s decision to remove Tidjane Thiam from the voters’ roll effectively disqualified the former Credit Suisse chief executive officer from this year’s presidential election, raising the risk of political instability in the world’s biggest cocoa-producing nation.
