Kenyan main opposition alliance has unveiled long-time opposition leader Raila Odinga as its flag bearer for the August elections, as it seeks to take over from President Uhuru Kenyatta.

Raila will face President Uhuru Kenyatta in the August vote, a repeat of the 2013 scenario which the incumbent won.

In an event held in the capital Nairobi, the National Super Alliance (NASA) opposition alliance attacked the government for not fulfilling the pledges it made during its campaigns.

NASA had been expected to make public its leader today following weeks of intensive deliberations between the different party leaders.

The 72-year-old has vied for the presidency three times before; 1997, 2007 and 2013, twice finishing second after the incumbents.

In the line-up unveiled by NASA, Kalonzo Musyoka take up the deputy president slot.

Presiden Uhuru will be seeking a second and final term in office.

Today’s unveiling is likely to shape up the political scene in the East African country ahead of the 8 August vote, as both the government and the opposition seek to attract voters.
