President Muhammadu Buhari has vowed to jail more of those who brought the nation into its present economic situation.

The President said this on Saturday at the Aso Villa in Abuja, the Federal Capital Territory.

He made the vow in an interview shortly after he returned to the country from his 10-day vacation in London.

The presidential aircraft arrived at the Nnamdi Azikiwe International Airport in Abuja, the nation’s capital, on Saturday evening.

President Buhari was received at the airport by some of his supporters, as well as top government officials and the nation’s service chiefs.

Shortly after his arrival, the President inspected a Guard of Honor mounted as part of activities to welcome him.

There was also a cultural display at the airport after which President Buhari left for the Presidential Villa amid tight security.

The President, who departed Nigeria for the United Kingdom on August 3, is expected to preside over a meeting with the security chiefs on Monday.

Prior to his trip, President Buhari had handed over power to the Vice President, Professor Yemi Osinbajo, in acting capacity while he was away.

Before taking off in London, President Buhari had put a call through to President Nana Akufo-Addo of Ghana, to sympathise with him on the death of former Secretary General of the United Nations (UN), Kofi Annan.

He noted the strategic influence of the diplomat in global affairs and his vision for the repositioning of the West Coast and Africa.

President Buhari also said that the exceptional leadership roles, humanitarian spirit, and contributions of the former UN chief to global peace and development would remain permanent in global history, especially his commitments to combating HIV/AIDS in Africa and launch of the UN Global Compact.

Mr Annan died on Saturday morning at the age of 80 in Switzerland after a brief illness.
