Nigeria is to hold a delayed presidential election this Saturday after the initial vote was rescheduled in a dramatic overnight press conference, five hours before polls were due to have opened.

The last-minute cancellation surprised the country and inconvenienced thousands of Nigerians who had travelled a long way to cast their votes.

It has also cost the economy $1.5bn (£1.15bn), according to the Lagos Chamber of Commerce and Industry.

The Independent National Electoral Commission (Inec) has given several reasons for the delay, including attempted sabotage and logistical issues such as bad weather and problems with delivering the ballot papers.

In a statement issued on the day of the postponement, the All Progressives Congress (APC) said the People's Democratic Party (PDP) wanted to halt the momentum of its candidate, President Muhammadu Buhari.

The PDP, whose presidential contender is Atiku Abubakar, on the other hand said Inec had delayed the election to create "the space to perfect their rigging plans".

Some analysts say the postponement is likely to harm both parties equally, as their supporters who had travelled home to vote last week will be unable to make another journey this weekend.
