An interesting article from guido concerning a yougov poll.
It makes for frightening reading for "thinking" labour supporters:
New YouGov polling has found that one third of Rebecca Long-Bailey’s supporters are “completely unwilling to compromise any Labour values, even if this means the party is unelectable.” Only 5% of Keir Starmer’s supporters refuse to compromise with the voters and just 4% of Lisa Nandy’s supporters prefer purity in opposition. Emily Thornberry did not have enough supporters to be polled…

Conversely, just 1% of RLB’s supporters are “willing to see large compromises on some Labour values if this makes the party more electable.” This compares to 16% of Starmer’s supporters and 19% of Nandy’s.

I did see a comment from another site describing Labour as a "circular Firing Squad". Kinda hard to dispute!
