As I've said many times before, just be patient and wait. There's over two and a half years to the next scheduled General Election and only when that occurs or an earlier one is announced will we know what Labour will do.

Clearly what Labour will do is adopt the most opportune position then for the election, a very sensible tactic, leaving the tories unable to focus criticism effectively meanwhile.
