God knows what Cromwell's reputation is ITTL.
Well, you know, Lord Rosebery, the Liberal PM who got the job when Gladstone retired the final time was pretty conservative in his liberalism, denounced the People's Budget as "pure socialism" (his words) and opposed House of Lords reform (I think) was still a huge fan of Cromwell throughout his life. He even paid to have them place the statue of Cromwell by the Palace of Westminster. Who knows, it may well be so that you can still admire Cromwell in this timeline.
