What do the Legg letters mean for the Kelly Review?

As the Legg controversy continues along its unedifying course, I can’t help but wonder what it all means for Sir Christopher Kelly’s review of the expenses system, due for publication in a few weeks’ time.  The plan is that the government will go through its recommendations, adopt any it likes, and then put them to a vote in the Commons.  But will Brown now back away from the more radical proposals, from fear of aggravating the Parliamentary Labour Party even further?  Will MPs now be more tempted to dismiss Kelly’s ideas out of hand?  This is, after all, yet another independent review, commissioned by Brown, which will contain suggestions you imagine will be less-then-popular with our political class.  I guess time will tell, but there’s the very real possibility that we will have had two prolonged investigations which result in little more than a further erosion of public faith in Parliament.
