Venezuela's electoral council has set a presidential election for April 14 to choose the successor to President Hugo Chavez.
Acting President Nicolas Maduro will run as the ruling party candidate.
The co-ordinator of the opposition coalition says Henrique Capriles is being offered that bloc's candidacy. Capriles lost to Chavez in an October election.
Chavez later anointed Maduro as his chosen successor before undergoing surgery in December for the cancer that led to his death Tuesday.
