Aldi has launched its first petrol stations offering cut price fuel. IGD Retail Analysis reported that the three trial sites in Austria had initially been selling diesel at 52 cents a litre. The petrol stations, located in the store car parks of the discount supermarket in the Salzburg area, were said to me unmanned, self-service facilities.

The petrol stations, which opened last week, were said to be offering the lowest prices seen on the continent for about three decades, with the cheap fuel sparking a price war and causing traffic jams all the way to Germany.

Prices had since increased, but remained about two cents below average.

A spokeswoman for Aldi said she was not aware of any plans for the company to open sites in the UK.
