In a statement made available to our correspondent on Wednesday, the high commission said, “We can confirm that we are collating relevant information, with a view to taking action against some individuals.”

The high commission, which said it deployed observers in six states, noted, “There were notable points of concern. Members of our observation mission personally observed violence, and voter suppression in numerous voting locations. We witnessed and received credible reports from other observer missions and civil society organisations of vote buying and voter intimidation, the destruction and hijacking of election materials and the general disruption of the process in numerous states including Lagos, Enugu and Rivers.

In addition, we observed incidents of harassment of journalists. Freedom of speech and a free press is crucial for a healthy democracy, and journalists must be able to go about their work without being threatened.

“The UK is concerned by the use of inflammatory ethnoreligious language by some public and political figures.

We call on all leaders not just to distance themselves from this kind of language, but to prevent those who speak on their behalf from doing so in this way.

“many Nigerians were prepared to vote despite being faced with intimidation and hostility.”
