In a speech to the European Business Congress in Deauville, France, Mr Miller offered little prospect of relief. He warned that the world was experiencing a fundamental shift in energy prices that will end at a "radically new level. We expect that the oil price will approach $250 per barrel in the foreseeable future".

Welcome to the new world. It is time to fundamentally change what we're doing and how we do it.

The chief executive of the world's largest energy company has issued the most dire warning yet about the soaring the price of oil, predicting that it will hit $250 per barrel "in the foreseeable future".

The forecast from Alexey Miller, the head of the Kremlin-owned gas giant Gazprom, would herald the arrival of �2-per-litre petrol and send shockwaves through the economy. His comments were the most stark to be expressed by an industry executive and come just days after the oil price registered its largest-ever single-day spike, hitting $139.12 per barrel last week amid fears that the world's faltering supply will be unable to keep up with demand.
