The national chairman of the party, Julius Abure made the call in a statement saying that INEC has given room for doubt in the credibility of the process.
Abure, said the inability of INEC to upload results after over 12 hours is worrisome and called it electoral robbery.
He said Labour Party is shocked by the revelations emanating from Rivers state after the presidential and national assembly elections which held on Saturday; where thugs believed to be agents of the state government invaded various polling units and collation centres, took away election materials including the results sheets, manipulated the BVAS machines and uploaded fake results in to the Central portal.
He also alleged that Lagos and Delta State votes have been severely manipulated.
