This Mount Everest of cash is not coming from you and me putting petrol into our cars because we have to. The oft-repeated joke in the industry is that it's not the Browne of BP (their boss, Lord Browne) who rips us off at the pumps but the other Brown, Gordon the Chancellor. Pre-tax petrol is cheaper in the UK than anywhere else in the EU - the fact is, we pay the highest petrol tax (about 75p in every pound) in the EU.
