I think all the party conferences this year are going to be fairly dramatic. The LibDem ones occasionally have great enthusiasm ("Prepare for Government", Cleggmania) which ends up not getting very far, but the Remove decision is I think in a different league: it could have a major effect. Admittedly splitting the remain vote and letting the Leave groups in by default, but a major effect nevertheless.

As you say, the Labour one will have a great deal to fight about over its Brexit policy statement that will drive the next Manifesto.

And the Tory one … well, let's see.
