By-Election In Newport West.

Following the death of Paul Flynn MP, a by-election is now due in Newport West.
I wonder what this signals for Mr Corbyn in a solidly Labour seat?
It is wholly improbable to believe that Corbyn could lose the seat but I doubt that the Labour will have much to crow about after the results are in.
(I would wager that our Jeremy will be in no hurry to move for this contest to be fought with his personal popularity at a record low.)
