In the end it doesn't really matter whether Labour was defeated by the Brexit factor or the Corbyn one because both will be gone by the time of the next election. For them the bird has flown as far as Brexit is concerned, and it is back where it belonged ie. a purely Tory thing, which Labout can no longer influence. This allows Labour to put the theme behind them, because what is now important is to develop a vision for post Brexit Britain. The Conservatives cannot satisfy all of the wishes of the diverse Brexit camp. People will wake up on Feb. 1st knowing they are out of the EU. but in reality the only thing which will have changed is that we have no representation left in Brussels - we will have become law takers, and not law makers. How long such a situation remains is unclear, but there is a lot of hard negotiation ahead, and a hard Brexit is still, very much, on the cards because the only way Johnson can get a deal so quickly is by giving way to all the EU's demands. Corbyn is right in one thing ie. they should allow time before electing a new leader, because they cannot afford a knee jerk reaction. They need to realize that socialism and realpolitik need to be combined and they need a leader who stands in the middle of those two - they also need a leader who can reconcile the interests of both the intellectual Islington elite and the traditional northern values. The new leader must be able to cultivate a relationship to the media, rather than being afraid of it - like Corbyn was. Looking through the list of possible replacements none of them really stand out (please not Diane Abbott !) - possibly Keith Starmer, possibly Yvette Cooper, but my wish would be David Lammy.
