It’s all a bit of a muddle. First, there was the retrospective repayments fiasco. Then the Leader of the House made it quite clear that she had no idea what would happen to MPs who did not repay their expenses. And now there is this godsend for the anti-Leggites. MPs are under enormous pressure to repay, but the increasingly chaotic Legg Commission offers them a possible get of jail free card. The saga has become this Parliament's version of Frank Sinatra’s never ending farewell tour; it is doing untold damage to the Commons' reputation.
