John Wight,
Jeremy Corbyn was a return to the old Labour Party responsible for the UK being in the doldrums for years.
Thatcher (brutally) got Britain competitive again in the world, and Tony Blair proceeded and made necessary changes that would have been difficult for the Tories.
Corbyn was limp in his efforts to stop Brexit and was so unappealing he couldn't win an election against Boris Johnson.
As Churchill said of Attlee, Corbyn "has much to be most about."
The UK should be hell-bent on getting back into the EU—something Labour could champion.
