First you claimed that Bogdanor said there were no rules for forming a govt after a second election, then you changed that to say there are rules, but they are inadequete and must be changed because there is a possibility that we won't get a workable government, and then you qualfied that by saying that the possible delay in forming a government would be dangerous, claiming all the while that the article you quoted backed all of this up.
I hope Vernon Bogdanor isn't reading this, because he'll be pretty pissed off at seeing his authority used to defend a series of shifting and bogus claims.
