I seem to remember there was a referendum and one side won and the other lost. There is such an urge to reverse the outcome of that, after seeing the 2 years since, from the electorate that the only party who have come close to calling for a second referendum is polling at about 9%, whilst the Tories have had their numbers hit by people apparently returning to UKIP because the plans aren't tough enough. Similar to how Corbyn isn't keen on the monarchy or Trident, but can't make it party policy because he doesn't have the numbers, there isn't the numbers in trying reverse or soften it. Partly because of Leavers in the party, who we did try and make it easier for local parties to get rid of, but you know deselections are what Stalin did or something and partly because of the wet lettuce rebels in the government, who don't rebel. But yeah, it's definitely Labour who are enabling Brexit.
I'd love to go back to the glory days where Corbyn was leading a party of protest and wasn't interested in power and show people how quickly he'd be criticised for literally the exact opposite.
