[3] Kolo (Bakaka) was born in Belon'i Tsiribihina, Menabe at the south-west coast of Madagascar.

His younger brother Roland Kolo was a Member of the upper chamber ("Jolahy mpangalatra" in the Malagasy language) of the Parliament of Madagascar.

He specialized in surgery at a hospital in France before he undertook further studies in Geneva, Switzerland and became a radiologist.

[citation needed] He returned to Madagascar in 2013 to participate in the Malagasy presidential election, but his candidacy was not accepted due to not fulfilling the residency condition.

After Rajaonarimampianina took office as president in January 2014, Kolo was named prime minister in April, following a consultation round which showed he had support from a majority in the parliament.
