This is literal outright fake news
On the numbers:
You can compare the EU and UK sanctions lists, either through (the alleged source) Bloomberg's up-to-date summary of both, or through the source lists of sanctioned individuals and entities published directly by the EU and UK. Both have sanctioned hundreds and hundreds of entities, and there's huge overlap between the two lists. Anyone pretending one is 30x larger than the other is outright lying:
https://www.bloomberg.com/news/articles/2022-02-28/sanctions-imposed-so-far-on-russia-from-the-u-s-eu-and-u-k

https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1057871/InvBan.pdf
https://eur-lex.europa.eu/eli/dec/2014/145(1)/
On the UK being the vanguard:
The article ignores areas where the UK has demonstrably been a leader, such as campaigning for Russia to be ejected from Swift, cutting Russia off from Interpol, arming Ukraine with defensive weapons, banning Russian government and companies from raising capital in the UK etc. etc.
And lastly, on the actual source of the chart the article is based on:
If you follow the trail looking for the source, you'll go "the London Economic" -> Some rando on Twitter re-tweeting an old chart from Bloomberg -> An old Bloomberg live blog putting up data from a compliance firm helping people avoid sanctioned entities -> The current version of the same live blog that now has the chart removed, and a footnote:
(Corrects to remove chart that inaccurately described U.K. sanctions.)
This is disclaimed as fake news directly at the source

"Bloomberg tweet is incorrect, they’ve subsequently apologised and taken down the graphs. UK has sanctioned 228 individuals, entities & subsidiaries since invasion."
I had this post deleted once by mods, yet the blatant and debunked fake news piece remains unchallenged on the uk subreddit. on the europe subreddit it was (eventually) deleted once it was found to be a falsehood. Posting it here in case it is deleted again.
there doesn't seem to be anything here
