Have you noticed that the price of petrol and diesel is creeping upwards again? OK the price of a barrel has risen slightly and the exchange rate against the dollar of the UK pound is a little worse. However, it seems someone is out to push prices up again to maximise profits.
Personally, I think fuel prices should be set nationally as in Iceland. In Iceland prices are the same wherever you go. I also think it is odd that anyone profits when fuels are essential to all of us. I'd run all energy supplies as nationalised industries, with any profits benefiting the consumer and not private share-holders. In this I'd put all essential services like energy, trains and buses. Clearly privatisation may encourage efficiency but making profits for private shareholders is stupid, in my opinion, when we are talking of essential services. These should be run for the benefit of all, not the few.
