Rowdy scenes have erupted in Mexico's Congress an hour before Felipe Calderon is due to be sworn in as president.
Deputies seized the speaker's platform and tried to block the doors of the chamber. Punches were thrown.
Members of the left-wing party, the PRD, say Mr Calderon won July's presidential election by fraud.
The disorder followed an unusual midnight ceremony in which the outgoing President, Vicente Fox, handed over power to Mr Calderon.
In the closed-door ceremony, Mr Fox handed the presidential sash to a military cadet to signify the end of his term in office.
Mr Calderon described the event as the start of the process of taking possession of the presidency.
However, opposition deputies argue he cannot become president without taking the oath of office, as outlined in Mexico's constitution.
Mr Calderon's spokesman has said the incoming president still plans to come to the Congress to complete his swearing-in.
But the BBC's Duncan Kennedy in Mexico City says whether he can finish the constitutional process in front of the nation at the building intended for it is now in some doubt.
Parallel government
Barricading the main doors to the lower house, deputy Adriana Diaz said: "Calderon is not coming in here, we are going to stop him.
"He is not coming in the front entrance. Thieves come in through the back door."
The Democratic Revolution Party (PRD) - whose candidate, Andres Manuel Lopez Obrador, lost the run-off by half a percentage point - has also massed crowds of supporters in the capital.
Thousands of riot police have been deployed around Congress to prevent them from moving in.
Mr Lopez Obrador last week launched a "parallel government" in Mexico City and held an unofficial swearing-in ceremony.
