For the adoption of neoliberalism, in nominally “left” political organisations, look at “Social” Deomocrats in pretty much any European country, and some of them are trying to conceal that by putting on a veneer of identity politics.

One very prominent example of a formerly leftist party turning full neoliberal while hiding behind a facade of identity politics are the German Greens.

Overall, classic working class issues have been largely abandoned by most self proclaimed left parties and movements, while they are busying themselves with identity politics based infighting. Not all of them have embraced full neoliberalism, but pretty much all of them subscribe to the extreme individualism that is central to the neoliberal ideology.
