Even a stellar international business career cannot prepare you for the hard realities of politics in Ivory Coast, where some are questioning the democratic credentials of the West African nation most famous for being the producer of much of the world’s cocoa and some of its finest footballers.

That is the painful lesson Tidjane Thiam is learning as he waits to see whether deal-making in the corridors of power and popular pressure from the street can rescue his bid to become president of Ivory Coast.

Seemingly relentless progress towards the election set for this October came to a juddering halt on 22 April when a judge ruled that the 62-year-old had lost his Ivorian citizenship by taking French nationality decades previously and not revoking it until too late to qualify for this year’s vote.

Moving back to Ivory Coast in 2022 after more than two decades in global finance, Thiam had immediately been seen as a potential contender to succeed current head of state Alassane Ouattara who, at 83, is now in the final year of his third term of office.

A scion of a traditional noble family and a great nephew of the country’s revered founding President, Félix Houphouët-Boigny, he had impressed as a top government official and minister in the 1990s, overseeing infrastructure development and radical economic reforms.

A military coup then pushed Thiam to seek a fresh career abroad, which culminated in high-profile stints as chief executive of UK insurance giant Prudential and then the banking group Credit Suisse.

But returning home at last, three years ago, he embarked on a steady advance towards the next Ivorian presidential election.

After the death in 2023 of former President Henri Konan Bédié, long-serving leader of the opposition Democratic Party of Ivory Coast (PDCI), Thiam was perfectly positioned to take his place and then on 17 April this year he was chosen as the party’s candidate for the upcoming presidential race.

That was no guarantee of victory, and especially if – as seems quite plausible Ouattara opts to run for a fourth term, backed by all the assets and advantages of incumbency and a track record of four successive years of annual economic growth above 6%.

However, Thiam stood out as the prime alternative.

As an opponent of the ruling Rally of Houphouëtists for Democracy and Peace (RHDP), he offered Ivorian voters the chance to change their government.

Yet with his centrist politics and solid technocratic credentials, his candidacy offered reassuring competence and the prospect of continuing the impressive economic progress that Ouattara has piloted since 2011.

Now that potential trajectory is blocked. If the court decision stands – and Ivorian law offers no option of appeal for this particular issue – Thiam will be out of October’s contest.

It is a race from which past court convictions have already excluded three other prominent opposition figures – former President Laurent Gbagbo, former Prime Minister Guillaume Soro and a former minister, Charles Blé Goudé – all central actors in the political crises and civil conflicts that brutally paralysed the progress of Ivory Coast between 1999 and 2011.

The prospect now is that Ouattara or any chosen RHDP successor candidate will approach the election without facing any heavyweight political challenge.

That can only deepen Ivorians’ already widespread popular disillusionment with the country’s political establishment.

This is against the wider context of a West Africa where the radical anti-politics rhetoric of the soldiers who have seized power in Mali, Burkina Faso and Niger already finds a sympathetic audience among many disenchanted young people.
