The Labour Party seems very pleased with itself following Sir Keir Starmer’s announcement that, if he were Prime Minister, his Government would freeze energy prices at current (August 2022) levels for six months and pay for it by a further “windfall tax” on energy companies. Apparently, opinion polls show overwhelming public support for such a measure, which is also endorsed by the LibDems and the SNP. Of course, it is easy to make such declarations when there is no chance of being able to carry them out.
