Scottish Power has become the latest energy company to raise its prices as splits appear in the Coalition over whether to roll back green taxes. Deputy Political Editor Chris Ship reports:
ScottishPower will raise the average prices of its duel fuel bills by 8.6%, gas by 8.5% and electricity up 9%.
The company said it is simply passing on to customers the costs it incurs for buying gas and electricity, supplying it to homes and dealing with customers, and emphasied that over a third of its 3.2 million customers on fixed rates would not see any increases to their bills.
Four of the 'Big Six' energy firms have now said the will raise their prices.
Labour leader Ed Miliband said the Prime Minister was offering a "panicked wheeze" on energy bills as splits emerged between David Cameron and Deputy Prime Minister Nick Clegg on green energy taxes, which energy companies are now passing on to consumers. Mr Miliband has promised to freeze energy prices if Labour wins the next general election.
A Downing Street spokesman said the coalition "is intact" after Mr Clegg admitted the Government disagreement over green energy levies.
Energy firms are due to give evidence to MPs on rising prices on Tuesday.
