Mr Na’abba, from Kano State, was speaker between 1999 and 2003.
He announced his resignation in a letter addressed to the APC Chairman of his Sharada Ward of Kano Municipal Local Government.
“This is to notify you of my resolve to resign from the All Progressives Congress (APC), effective today 5th December 2018,” he wrote.
“My decision to resign from the party follows the cavalier manner in which both the Federal Government, States controlled by the APC and the APC itself are being run, as a result of which anybody who has eyes to see only sees doom and not prosperity for our dear country.”
The politician based his decision on the manner congresses and primary elections were conducted in the party.
He said there was clearly no doubt in his mind, and the minds of visionary Nigerians, that the APC administration is characterised by “lack of consultation, crass incompetence, lack of vision, arrogance, and dangerous fixation.”
He made reference to defections in the National Assembly as a sign of the failure of the APC.
“It is a measure of the incompetence of the APC government that after all is said and done, it has lost a Senate President and a Speaker of the House Of Representatives and many others for reasons that border on meanness, lack of simple management skills and capacities and a great measure of arrogance.”
