In last night's Commons votes on reforming the Lords most people thought that the 80% option would come out on top, if any of them did. As we all know, the 100% elected option triumphed. But if you study the division lists it has become clear that more than 90 Labour MPs voted 'no' to 80% and then trooped into the 'yes' lobby for 100%.
It could be, of course, that they did it on principle and only voted for the option they really wanted. I suspect, however, that most of them did it to bugger up the whole process, as they knew it would then produce a lengthy Mexican stand-off with the House of Lords.
