The occurrence of oil spill at Alaska has led to increase in the petrol prices in the global market and they could reach to £6 a gallon, as believed by some experts.

Since the advent of the year, the petrol prices have been rising; firstly due to the rise in the flue duty and secondly because of increase in VAT to 20%.

The average price of unleaded petrol and diesel at the pumps of Britain on Monday was 127.8p and 132.05p for a litre, respectively. Four forecourts have set petrol price at 140p a litre, while some 400 such places are selling unleaded petrol for 130p a litre. The price, as per experts, could reach to 132p a litre, which is equal to £6 per gallon.

The rise in the petrol prices has been faced after the closure of the Trans-Alaska Pipeline System following leak. It supplies 15% of America's oil. The oil spill raised the price of Brent Crude futures by $2.13, or 2.3% to $95.46 a barrel in London.

However, the speculators are endeavoring to surge the prices of petrol to $100 a barrel, as warned by John Hall, of John Hall Associates, an independent energy consultant.

"It is like a bubble, there will come a point in the spring when speculators will pull back. But in the short term the rise in oil prices and taxes is bad news for motorists", he said.
