We appear to be very thin on explanation where the "energy price Guarantee" is concerned. I have the feeling that Truss would have heaved a sigh of relief that the discussion of this was interrupted in Parliament.
One fact I think we should keep in mind is regarding Truss's Campaign fund for the leadership. The largest single donation came from Fitriani Hay, wife of James Hay, a former BP executive, who donated £100,000.
You may feel that matters or that it doesn't. The acceptance of this money does beg the question, "why is the PM so opposed to a new windfall tax". She may have opposed this anyway. However, taking this money to fulfil personal ambition makes it difficult to believe it hasn't influenced her decision.
Although Ms Truss is adamant she is lowering taxes, she intends we pay for the freeze in energy prices over the next 20 years. Apparently, taxes are not taxes when they are paid for by us all through our energy bills.
