The First Minister, of course, did not answer the question. Five per cent of an electricity bill goes in profits to the electricity companies, 20 per cent in green taxes. So, the First Minister is completely wrong. But however bad things are at the minute, things are going to get worse, because the Office for Budget Responsibility forecasts, which accompanied the budget papers this year, show that environmental levies will rise from £10.7 billion this year to £13.5 billion by 2022. So, that means that green taxes will then be over £200 per annum for the average electricity user and a third of power bills.

The introduction of smart meters is going to add another £11 billion to that. That's £84 a year extra for the next five years for every household. Also, an extra £2 billion is going to be spent on upgrading transmission lines and infrastructure to cater for remote windfarms. That adds another £25 per household. So, I repeat my question, which the First Minister didn't answer the first time around: how can we justify loading these charges upon the poorest and most vulnerable in society?
