Why Venezuela is short of bank notes

The opposition in Venezuela has won a majority of seats in the National Assembly, overturning nearly two decades of dominance by the ruling party of President Nicolas Maduro.

Mr Maduro's popularity has dropped fast in the last year according to many opinion polls, mainly because of the country's economic woes - worsened by the fall in the price of oil in international markets.

Venezuela has one of the highest inflation rates in the world and has been suffering of chronic shortages of many basic goods in recent years.

The inflation is now so high that there aren't even enough bills in circulation to cope with the population's needs.

The BBC's Daniel Pardo explains why this is happening.
