KEY POINTS:
MEXICO CITY - A leftist opposition leader who claims he was robbed of victory in a July election was sworn in as Mexico's "legitimate president" in a challenge to his conservative rival, President-elect Felipe Calderon.
Andres Manuel Lopez Obrador donned a red, white and green sash like those used by Mexico's presidents and promised supporters that his parallel government would work for the poor.
The ceremony in Mexico City's central Zocalo square has no legal weight but could mark the start of new street protests.
