The cat litter tray of history

I've just seen Liverpool Lib Dem Councillor Richard Kemp make a Conference speech in which he called for their proposals for local government to be "condemned to the litter tray of history". Another speaker moving reference back of the report said, "There is nothing very much wrong with this paper.... because there's nothing very much in it". How very satisfying that the Party that only actually runs anything at all at local government level...seems to know sod all about it.
