I have always hated retrogressive legislation. Ever since they did it to me (cost me about 2 million).
It sends a very bad message to large corporations. "You cannot do business in the UK".
I don't like the idea of "borrowing".
I think a Voluntary Donation of around 100 billion from the huge energy corporations is the best idea.
This would help the UK over current problems such as energy and rising prices.
In return those companies would be given guaranteed smaller tax amounts from 2025 onwards until the savings to them amounted to a similar sum as the donation.

BUT - I know nothing.
