Tinubu, who was declared the winner of the February 25 presidential election, will be sworn in by the Chief Justice of Nigeria, Olukayode Ariwoola, at Eagle Square, Abuja on Monday.

Bola Tinubu is set to be sworn in as the new president of Nigeria on Monday amid pressure to resolve sustained economic and security issues plaguing the country.

71-year-old Bola Tinubu won February's election with a promise to renew hope - but he faces tough economic and security challenges.

He will take over from two-term President Muhammadu Buhari amid a high inflation rate, record debt levels and increasing cases of kidnap-for-ransom.

Mr Tinubu's victory is being challenged in court by his two closest rivals.

They alleged that the outcome was manipulated.

But the outgoing president, who did not run in the election after eight years in power, said the results were "credible" and the vote was "fair and transparent".

The hearing of the main arguments will commence on Tuesday but the court's decision is not expected until September.

Nigeria's electoral commission admitted there had been "glitches" during the ballot but refuted claims that the elections were not free and fair.

Tinubu has been known for exerting power from behind the scenes and using his extensive network to back candidates for office.

However Tinubu only won the elections with 37% of the vote, the lowest share since 1999.

Dignitaries from across the continent, including South Africa's President Cyril Ramaphosa, are expected at the swearing-in ceremony in the capital, Abuja, reflecting the significance of the event.

During his tenure, Buhari had promised to resolve issues of corruption and insecurity but left many disappointed.

The country is suffering under economic distress that has resulted in two-decades of high inflation, record debt, weak currency, shortages of foreign exchange and fuel.

Violence is rampant in the country with separatists and gangs wreaking havoc in the southeast which has left many Nigerians feeling insecure.

The oil-rich nation also faces the major challenge of swapping crude oil worth billions of dollars for gasoline which it then needs to subsidize for its domestic market. This has contributed to ballooning debt.

The incoming government will also need to prioritize issues concerning security which have seen a significant rise in recent years.
