Diolch yn fawr, Llywydd. The temperature in this Chamber may rise tomorrow, but I wonder if the First Minister's seen that the Met Office forecasts for outside show that we are likely to have sub-zero temperatures for the next week or two. I wonder if he also saw on Monday in The Guardian that there was a report saying that electricity and gas prices have risen in the last 20 years by three times the rate of inflation and the average household now spends £562 a year on heating and lighting. What it didn't say was that this is overwhelmingly due to the rise in green taxes, which will cost households almost £150 a year from next year, and they've risen by two thirds since 2014 and are now 20 per cent of the typical electricity bill. Considering that a quarter of the households in Wales live in fuel poverty, how can we justify loading these charges upon the poorest and most vulnerable in society?
