2017 was Labour's most right-wing manifesto in recent history (maybe ever). Their signature policy was
literally a tax cut for (certain) rich people (mostly those from rich families), their leader supports and is one of the main causes of Brexit, generally considered a right wing project, and they're being investigated and soon to be found guilty of rampant, institutional racism, also generally considered right wing (the only other British political party to do similar was the BNP).
Incidentally, who are these big beasts?
