Pressure is mounting on Wiper party leader Kalonzo Musyoka to rejoin Raila Odinga's Azimio la Umoja One Kenya Coalition party.
Despite launching his presidential bid and unveiling Andrew Sunkuli as his running mate, Kalonzo's party affiliation to Azimio has raised eyebrows in the political class.
Wiper legislators are now urging Kalonzo to join forces with Azimio, citing the party's affiliation as a formality.
However, Kalonzo's confidants suggest that he may be considering rejoining the coalition, which had promised him the Chief Cabinet Minister position if Raila Odinga becomes President.
As the road-map to the August polls gains shape, Kalonzo's next move is eagerly awaited, with many expecting him to announce his decision soon.
