I have seen many people praise Nick Clegg's performance. Apart from the Ashcroft/Whelan line all he seemed to be saying was: "It's not fair". To be fair to him, he was completely drowned out by MPs of both the other parties, but he should have sat down and waited for the Speaker to calm things down.
UPDATE: Cameron's pleas for unionised workers to break the strike appear to be paying dividends. BA has just announced that it is flying more planes than expected on Saturday after more staff have volunteered to work.
