Two major political parties have staged a walkout from the national collation facility in Abuja.

The Labour Party and the Peoples Democratic Party, the two dominant opposition parties, abandoned the International Conference Centre venue of the collation after trying unsuccessfully to convince Mahmood Yakubu to announce results previously uploaded to the server of the electoral body INEC.

Controversies have continued to trail the announcement of results from across the country by Mr Yakubu, the INEC chairman, after parties said they believed the results being announced did not reflect what transpired at polling centres across the country. Some of the agents also mentioned how some results were specifically different from what had been announced at unit, ward and local government area levels.

A spokesman for INEC did not immediately return a request seeking comments about how the electoral office planned to respond to the demonstration of Labour and PDP.
