WTF is going on with UK Labour and UK politics in general?

Brexit has shifted the Overton window so far to the right that Labour are now Thatcherites, and the Tories are full blown fascists.

Margaret Thatcher was a ‘visionary’ says Labour’s David Lammy

The shadow foreign secretary’s words are likely to infuriate the left of his party.

@ccferrie @cstross OTOH, Tony Blair was a Thatcherite from the start; plus ça change
@acb @cstross perhaps, but he was never so explicit about it
@ccferrie @cstross Blair talked a vague, noncommittal things-can-only-get-better message (stripped of any vestiges of socialism) whilst continuing a Chicago-school trickle-down agenda. Starmer is talking up Thatcher-era Toryism as obvious talking points to the elderly homeowners who cling to the Tories. What Labour does behind the scenes, in circumstances unlike the 80s, may reflect this to varying degrees.
