Energy bills are likely to go up in the longer run if Labour come to power, the chief executive of British Gas owner Centrica has told ITV News.
Leader Ed Miliband pledged to freeze energy bills for 20 months if his party wins the general election, but Sam Laidlaw says the plans are likely to scare investors, thereby raising the cost of capital for energy companies and in turn leading to higher bills.
Asked if the plans were already having such an effect, Mr Laidlaw said general "political uncertainty" was raising the cost of capital for energy firms.
