Sources say Mburu passed on at MP Shah Hospital where he was receiving treatment after a long battle with gastric cancer on Wednesday.
His death has dealt a big blow to the media fraternity and the country at large as his show which was loved by many.
Mburu had recently declared his bid to vie for Maragua Constituency MP seat.
The radio personality's programme dealt with socio- and geo-political issues, and was popular across audiences.
The 15-minute show ran on weekdays at 8pm, with repeats the following morning at 6.45am.
Until his death, Mburu had served Royal Media for many years and was among pioneers in radio commentary.
