The National Organiser of the ruling New Patriotic Party (NPP), Sammi Awuku has attributed the current changes in the country’s electoral system to the 2012 election petition initiated by the NPP through the then candidate Nana Addo Dankwa Akufo-Addo and running mate, Dr. Mahamudu Bawumia as well as then NPP National Chairman, the late Jake Obetsebei Lamptey.
