Venezuela's National Constituent Assembly President, Delcy Rodriguez, has repeated her call to the five opposition governors elected in last weekend's regional polls, to be sworn in.
"It is enough to contradict the institutionality and the Constitution of the Bolivarian Republic of Venezuela. We are waiting for them to take the oath," Rodriguez said.
The Venezuelan President Nicolas Maduro's United Socialist Party of Venezuela, PSUV, won Sunday's elections, taking 18 of the 23 state governorships in the vote.
Rodriguez urged the opposition governors to come forward while she was attending the swearing-in ceremony for Henry Rangel, who has been re-elected as Governor of the state Trujillo.
According to a decree, governors-elect who have not previously been sworn in before the ANC cannot be proclaimed by the Legislative Councils in their states.
On Wednesday, the ruling party's governors were sworn in.
But the five opposition representatives decided not to go to take the oath, despite the directive from the Assembly.
However, they are at growing odds with one another over the issue.
Among the dissenters in the opposition ranks, is the governor-elect of Nueva Esparta state, Alfredo Diaz.
Diaz represents the opposition Democratic Action, AD, and favors taking the oath. His party had planned to ask the Democratic Unity Roundtable, MUD, to reconsider its position against recognising the ANC.
In an interview with Noticiero Digital, he warned that if they did not, they could lose their governorships, "If the only alternative we have left to not give up our spot is to take the oath before the ANC so that they do not arbitrarily take our space, we must do it, I ask you to join us, it is not a matter of bowing our heads, or of giving up."
Maduro also has said governors who do not subordinate to the ANC will not be able to take up their posts.
