Vice-President Yemi Osinbajo says he approved contracts of the Nigeria National Petroleum Corporation (NNPC) when President Muhammadu Buhari was on medical vacation in the UK.

Ibe Kachikwu, minister of state for petroleum resources, had accused Maikanti Baru, group managing director (GMD) of the NNPC, of awarding contracts without due process, an allegation that the corporation denied.

But in a series of tweets 0on Thursday, Laolu Akande, spokesman of the vice-president, said Osinbajo approved the contracts as part of necessary actions to deal with a backlog of unpaid cash calls and incentivise investments.

“In response to media inquiries on NNPC joint venture financing, VP Osinbajo, as Ag President approved recommendations after due diligence & adherence to established procedure. Action necessary to deal with huge backlog of unpaid cash calls which Buhari administration inherited and also to incentive much needed  fresh investments in the oil & gas sector,” he tweeted.
