My only conclusion (and the NLR seems pretty explicit here) is that many on the left would be happier with a Conservative government.
I've been spending time with my 1980 Labour Draft Manifesto. It is a reassuringly bonkers document that shows just how far the Labour Party has come. It is badly designed, poorly researched and badly written. It is fine to sneer at the language of this week's manifesto, but any idea that there was some golden age of political language before the arrival of the spinners is just nonsense.
There are some choice policies: "Labour will seek to transfer all privately rented property (except where an owner-occupier lets part of his own home) into social ownership".
"We shall establish a significant public stake in each important industrial sector, inclusing major companies in such sectors as pharmaceuticals, medical equipment, micro-electronics, construction and building materials."
And there are some interesting timeless concerns: "There is the threat to our civil liberties, for example, from the growth in the use of computer data banks, surveillance equipment, and the rest." Don't you love the vague threat of "and the rest".
Some proposals have come around again, such as giving extra funds and lending powers to the Co-Operative Development Agency.
