Key government officials have been observed to begin gathering at the main electoral centre in Kenya’s capital, Nairobi, indicating preparations for a key announcement.

Foreign Affairs Minister Amina Mohammed and other key allies of President Uhuru Kenyatta have arrived at the Bomas of Kenya, which hosts the Independent Electoral and Boundaries Commission (IEBC) national tallying centre.

Presenters on the privately-owned Citizen TV, which is airing a live feed from the centre, said the “mood” there had “changed”, and that this might indicate that a “major announcement was imminent”.

Senior diplomats from various missions were also spotted arriving at the venue.

The IEBC said it would announce the final presidential outcome soon after the process of verifying and tallying the results is completed on 11 August.

Results published on the commission’s website show that President Kenyatta has a commanding lead over his main challenger, Raila Odinga.
