Sadly, Johnson is correct. Rewarding donors is pretty much a cross-party tradition which Johnson and his pals are taking to its logical conclusion:
William Manuel Morris, Baron Morris of Handsworth, OJ, DL (born 19 October 1938), generally known as Bill Morris, is a former British trade union leader. He was General Secretary of the Transport and General Workers’ Union from 1992 to 2003, and the first black leader of a major British trade union.https://en.wikipedia.org/wiki/Bill_Morris,_Baron_Morris_of_Handsworth
In 2001, here are the top donors to the Labour Party:
Bill Morris’ TGWU was in 5th place, donating £200 000 in just one year. Most of the donations come from trade unions. There are 169 Labour Lords. I’d need a research assistant to find how many are former donors.
There are also 84 Lib Dems. Lord Sainsbury gave them £8 million in 2020 alone.
There are 26 Lords Spiritual, all C of E, I suspect who are no doubt donating their prayers to save most Tory MP’s from the fires of Hell.
Reform is unlikely and the only way out is out.
