Unassuming. Stubborn. Steely, controversial and tenacious; these are the five words that come close to describing the contrasting figure of former Independent Electoral and Boundaries Commission (IEBC) chairman Wafula Chebukati.
He strikes a fixed gaze, but if you look keenly he's quite shifty. You can hardly get a byte off him.
In six years, he has run three presidential elections, stoking controversy at each turn. In the wake of each, it was praise and condemnation in equal measure, cheers and jeers, honour and dishonour.
