The runner-up in Mexico’s presidential election, Andres Manuel Lopez Obrador, has alleged that winner Enrique Pena Nieto’s campaign used laundered money.
He said he had evidence that Mr Pena Nieto’s Institutional Revolutionary Party (PRI) had used illicit money.
The PRI rejected the accusations as “flagrant defamation” by Mr Lopez Obrador, who is legally challenging the result of the 1 July poll.
