The position was formerly held by Ambassador John Kijazi, who died in a Dodoma hospital mid-last week and was buried at his Korogwe home village in Tanga Region.
A State House press statement issued yesterday said the president also conferred upon the incoming Chief Secretary the rank of Ambassador, in like manner as most of those who came before him.
Dr Kakurwa, whose appointment took effect yesterday, is expected to be sworn in tomorrow at the State House in Dar es Salaam today.
