Nearly three weeks after Mexico's presidential election, the candidate who came in second place is still refusing to admit defeat.

Andres Manuel Lopez Obrador continues to call for mass rallies to challenge the official result which gave Enrique Pena Nieto the most votes.

Pena Nieto's Institutional Revolutionary Party (PRI) has admitted that it spent $5m on gift cards for party workers, but it maintains that they were never meant to be given to voters.
