[JURIST] Mexican President Vicente Fox announced in a nationwide TV broadcast [official transcript in Spanish; recorded video] Wednesday night that he had accepted the resignation of Mexican Attorney General Rafael Macedo De La Concha. De La Concha had been at the forefront of efforts to prosecute popular Mexico City mayor Andres Manuel Lopez Obrador [advocacy website] for contempt, strip him of political immunity, and sideline his candidacy in the country's 2006 presidential elections. While the Mexican Congress removed Obrador's immunity, the charges against him have proved legally problematic {JURIST report], and last weekend hundreds of thousands of Obrador supporters demonstrated in his favor in Mexico City. Fox, who is not running for re-election next year, promised that the presidential vote would be free and fair and that candidates from all parties would be able to run. Polls currently show Obrador as the frontrunner. VOA has more.
