Dr Kwa was among other distinguished guests who paid tribute to Late Dr Gelu.
From humble beginnings to reaching the pinnacle of his career, Dr Kwa said late Dr Gelu was a man to go to in terms of political advice.
"Dr Gelu has served the country with distinction,” said Dr Kwa.
"He has left a very big vacuum in the DPLLGA and the country as a whole. You will find no sadness in Dr Gelu. He will always smile and treat everybody the same."
