Two of the main issues expected to dominate Mexico's presidential election on Sunday are the economy and the country's "War on Drugs".

Mexico's economy is growing at a rate of four per cent, but 20 million youths are out of school and out of work.

Meanwhile, more than 50,000 people have been killed since December 2006, in the fight against drug gangs and organised crime.
