Talking to a committee of MPs yesterday, he added that record oil prices, as well as demand from other countries across the world, are also affecting the cost of resources.

Mr Laidlaw's comments come after energywatch recently urged the government to take "three steps" in order to tackle the rising cost of gas and electricity.
The organisation urged MPs to begin an initiative to remove the link between the price of gas and barrels of oil, while it also called for the Competition Commission to investigate the energy market.
