On Friday the protests extended into the national assembly where outgoing president Vicente Fox was scheduled to deliver his final state of the union address. But before Fox arrived, lawmakers from Lopez Obrador’s PRD political party stormed the podium and seized control of the proceedings. They began chanting “Vote by vote.” When Vincente Fox arrived he announced he could not give the address.

• Vicente Fox: “Faced with the attitude of a group of legislators that makes it impossible to read the speech I have prepared for this occasion, I am leaving the building.”

Fox later delivered the speech on television.
