Never going to happen ....
firstly Lagos and Abuja are like Rio and Brasilia .... brasilia is the capital of Brasil but everyone goes to Rio to party and for business
same with Lagos..... Abuja is much more cleaner , better run and planned ... but lagos is where the money is .... lagos is the commercial capital
Politics is done in abuja, but money is made in Lagos, and lagos has the best party scene , no one is going to abuja for tourism , every Friday all the local flights from Abuja are packed with people who work there going to Lagos for the weekend ...
also with Eko Atlantic being built from the sea there is a lot more space being generated for more people ...
