CoffeeHouse has just been brought up in the Commons – Mark Harper has challenged Ed Davey to clarify what on earth Lembit Opik is on about. Is it true, he asked, that Lembit is not a rebel as he claims because the LibDems plan to abstain on the issue of a referendum on the Lisbon Treaty? Davey cryptically said that we will have to wait and see – and said that one option open to them was “constructive abstention,” whatever that is. Answer: no one in that disorganised party has the faintest idea what their policy is. They can’t even decide if they will sit on a fence.
