Ex-candidate quits Mexico's main leftist party

MEXICO CITY — The man who led Mexico's main leftist party in the past two presidential elections says he is leaving it behind.

Andres Manuel Lopez Obrador told supporters at a rally in Mexico City on Sunday that the break with the Democratic Revolution Party and its allies is amicable, but indicates he may create a new party out of another organization that backed him, the Movement for National Regeneration.

Lopez Obrador was Mexico City mayor before seeking the presidency in 2006. He narrowly lost that election and tried again this year, coming in second again. He alleges irregularities in both elections.
