He dismissed the reports in a statement on Monday by his Media aide, Habib Aruna.
Reports in some quarters claimed that Ambode was disappointed he did not make the ministerial list President Muhammadu Buhari submitted to the Nigerian Senate.
Buhari instead nominated ex Lagos Governor and immediate past Minister of Works, Power and Housing, Babatunde Fashola, and the Managing Director of Nigeria Inland Waterways Authority (NIWA), Sen. Olorunnimbe Mamora.
Reacting, Ambode described plans to leave the ruling party as totally untrue and an attempt to malign him.
Aruna said: “We enjoin the general public, particularly Lagosians to disregard the planted news by some faceless and mischievous individuals in some unknown blogs, who are hell-bent on creating an acrimonious situation, spreading fake news that the immediate past governor of Lagos State, HE. Akinwunmi Ambode has dumped the ruling All Progressive Congress (APC) for the PDP.
“The news is fake. The former governor is firmly a member of APC, working in his own capacity to see that the progressive ideas and the next level agenda of President Buhari succeed”.
