The main opposition party formed the alliance called the Coalition of United Political Parties (CUPP) on Monday.
Their collective aim is to defeat President Muhammadu Buhari’s All Progressives Congress (APC).
But Keyamo does not take them seriously.
“Some political parties made up of just husband and wife have signed an MOU with PDP to form a ‘grand coalition’ against PMB in 2019. This is pure deceit,” he wrote on Twitter.
“PDP has only succeeded in registering a few more members into its fold. It’s not a ‘grand coalition’. It’s just membership drive. “Nobody is deceived: In 2013 four MAJOR parties with ELECTED governors and parliamentarians fused into ONE whole.
“The comedy we are seeing now is that PDP have sucked in those ‘briefcase’ parties who are going to drop their identities and support a PDP CANDIDATE. It’s laughable desperation.”
