The senator representing Borno Central,Alhaji Ahmed Zannah, died Saturday in Abuja at the age of 60.
The All Progressives Congress (APC) senator was originally elected on the platform of the Peoples Democratic Party (PDP) in 2011 after defeating former Borno State Governor Ali Modu Sheriff, who contested on the platform of the defunct ANPP.
Zannah who was re-elected in last month's election, succumb to stroke yesterday.
He returned to Nigeria recently from medical treatment in London.
He was a vitriolic critic of President Goodluck Jonathan over his poor handling of the Boko Haram menace in the North-East which led to the dislocation and capture of a substantial population of his constituents.
Describing Zanna's death, Senate President David Mark stated it is a big blow to the senate and the nation.
The Senate and the Chairman of its Committee on Environment and Ecology, Dr. Bukola Saraki expressed sadness at his demise.
Mark in a statement through his Chief Press Secretary, Paul Mumeh, stated Zannah's death was one too many.
He is the fifth member of the 7th Senate to pass on.
The Senate President said: “Senator Zanna’s death coming a few days after the demise of Senator Uche Chukwumerije is a big blow to the Senate and the nation. This is certainly not the best of times for us. These deaths in quick succession are heart breaking.
“We cannot question the will of the Almighty. We can only ask that our Creator give us the fortitude to bear this sad loss and grant the deceased eternal rest.”
