Explainer: What you need to know about Azimio's petition at Supreme Court

Azimio La Umoja candidate Raila Odinga and his running mate, Martha Karua, filed a petition challenging the outcome of the presidential election at the Supreme Court on Monday, claiming the election was manipulated to favour President-elect William Ruto.

They claim among things, that Dr Ruto did not garner 50 percent plus one vote required for a candidate to be declared the winner and that the electoral commission chairman Wafula Chebukati announced the outcome without tallying and verifying results from 27 constituencies, which would have affected the final tally.
