There have recently been a number of attempts to smear the reputation of Winston Churchill. These have ranged from daubing his statue with graffiti accusing Churchill of being a “racist”, to a recent conference at Churchill College. During the latter event Churchill was, again maligned and the British empire was said to have been worse than that of the Nazis.
For a more balanced perspective on Churchill I would recommend a publication by Policy Exchange which points out the many inaccuracies in the view of Churchill promulgated by the conference at the college which bares his name.
This link deals with the decision of Churchill College to end the one-sided discussions during which Churchill’s reputation was maligned, https://policyexchange.org.uk/churchill-college-has-made-a-wise-decision-in-closing-down-the-working-group-on-churchill-race-and-empire/, whilst the second contains a link to a more balanced assessment of his reputation https://policyexchange.org.uk/publication/the-racial-consequences-of-mr-churchill-a-review/.
