Corbyn should listen to his party - we've seen how they bled votes to the LDems & Greens
It’s too late for Corbyn on this.... If he came out now and supported a 2nd referendum, who would believe he was being genuine? He would be seen as being weak, and forced against his will to parrot support for something he doesn’t believe in? Who could vote for that!!
Labour brexiteers supporters would feel betrayed, with a fair few going to Farage... and those who had moved to the LDs or Greens will probably stay put. Voting for a Lexiter who’s been coerced into supporting a second referendum is hardly the best way to stop Brexit is it!...
Besides, things have moved on.... The best way to stop Brexit is for the LDs and Greens to form a hard or soft electoral pact, and to campaign on the basis of Revoke if 50% of more voters back remain parties in the GE....(and a referendum if not)
This would:
a) avoid prolonging the agony, and appeal to those disengaged from politics who just want Brexit over (and for whom ‘no-deal’ appears to be the way to deliver this - albeit they are tragically wrong in this regard)
b) cement ex-Labour remainers to their cause, outflanking any calls by Labour for a referendum
c) with the momentum generated, bring over Remainer Tories on board desperate to avoid the “devil and deep-blue-sea” of no-deal and Corbyn
d) ensure every Remainer feels their vote counts, even in Brexit heartlands... boosting their votes in the process.
e) give an effective riposte to brexiteers who claim Revoke is undemocratic.
Given 40% of voters at the EU elections voted for explicitly Remain parties, this isn’t pie in the sky stuff!
