The media are rewriting what happened at the last election, in support of the Blairite campaign against Jeremy Corbyn for Labour Leader.
Don't buy it, guys.
Under the supposedly unelectable Ed Miliband Labour votes in England rose by 3.6%.
Labour got hammered because a) Libdems switched to Tory, and b) Scottish Labour had a right-wing Blairite as leader.
So the unrelenting newspaper and BBC narrative that a left-wing Labour Party is unelectable is unsupported by anything remotely resembling a fact.
