The upset from Labour conference this teatime is the evening Compass event.
Compass is putting the Greens' MEP and party leader Caroline Lucas on a platform with Harriet Harman ... all in the spirit of their new cross-party magnanimity. Compass believes it should talk constructively to the Lib Dems, the Greens, Respect, and so on.
But detractors are mumbling – Labour is fighting a tough battle to keep Brighton Pavilion out of Caroline Lucas's hands – and Compass is giving a platform to the opposition. Talk has been of Harman pulling out. Likelihood is she won't, to avoid a fuss. But the Pavilion Labour candidate Nancy Platts – trying to replace current Labour MP David Lepper – is not on the guest list.
I've just spoken to Gavin Hayes of Compass about this. First he makes the not-unfair point that Lucas is speaking elsewhere this evening, including at a Fabian event, and that organisation is affiliated with the Labour party too.
Second he says: "If you look at our No Turning Back document, of the 10 policies we proposed, six were Lib Dem, nine were green and none were New Labour ... "
That's Compass saying that, more in sorrow than in anger, they may have more in common with Lucas than with the Labour lot.
