this is what Was has to say on the putative Labour-Green coalition in Reading (which is unlikely to happen)
Labour simply cannot afford to give the Greens anything that can be put on a leaflet in Park ward as a Green policy win no matter how small which means that unless they insist on a formal and publicly available document listing in detail what has been promised by Labour in return for power, they will find that once in charge any promises made will not get a veggie sausage to show for it.
Why? Labour are terrified of losing their totemic ward of Park completely to the Greens. Sure Jon Hartley will come up with some bogus reason why he will be stepping down to dodge personal embarrassment but Labour will fight like rats in a sack to avoid losing Martin Salter's heartland ward. It means there can be no Green initiatives that can be put to the electorate.
