The Mexican elections may be over but the demonstrations continue. This Sunday marches took place in several cities as protestors took to the streets against the winner of the most votes, Enrique Peña Nieto. Marchers claim his party, the Institutional Revolutionary Party, used illict funds and bought votes during the election campaign. Peña Nieto won more than three million votes more than his nearest rival but the protests are scheduled to continue.
