According to figures released by the ministry, travel was the single biggest government line item from 2012 to 2014, at N248bn ($1.25bn) for the three years combined (the ministry did not provide annual figures). This is equivalent to an extraordinary 18 per cent of total government spending [Emphasis added].
……. A 2012 investigation by Nigerian newspaper Punch found that wealthy Nigerians spent $6.5bn on private planes between 2007 and 2012, making the country the biggest market for them in Africa.
Not all of them were bought with private funds. Under former president Goodluck Jonathan, Nigeria’s Presidential Air Fleet (PAF) acquired several new private jets, bringing its total to 11.
And you know a non-trivial proportion of these “study tours,” conferences, and meetings were either expensive shopping trips on the government’s tab or ploys to earn inflated per diems.
This is an instance where I’d endorse a move to “leapfrog” meetings, workshops, and conferences.
