Nigeria’s era of big spending for election is disappearing

There’s just a month to go until Nigerians go to the polls. At least 91 political parties have registered and more than 70 have put forward presidential candidates.

Elections there have always been big business. Political parties spend hundreds of millions of dollars in publicity, logistics and even vote buying.

But reduced spending has affected campaigning.
