The FEC is expected to meet the National Executive Committee (NEC) to discuss the proposals.
Most political parties in the country are re-organising for the 2016 general elections with the largest opposition party, New Patriotic Party (NPP), leading the pack having elected its flagbearer and majority of its parliamentary candidates.
