None of those mentioned stand a reasonable chance of being elected (other than by Nu Labourites). They're damaged goods.i'd suggest as a start that a 'proper leader' is one who stands a reasonable chance of being elected - bumping along at 25%, turning a 45 year solid, 15,000 majority labour seat into a marginal, and being less trusted among Labour voters than David Cameron would perhaps indicate that Corbyn is being less than successful at being a 'proper leader'...
others, of course, may hold differing views.
