Serious questions to answer
The fanfares, the ermine robes, the tiaras. She's seen it all before. Her Majesty has delivered the Queen's Speech no fewer than 56 times but never has there been a day quite like this - a day when the monarch didn't just open Parliament - she was visiting the scene of an alleged crime.
This year - as every year - MPs slammed the door in the face of Black Rod - the man sent to summon them. It's a historic symbol that no-one tells our elected representatives what to do.
"Hats off strangers" is the cry when the Speaker's procession goes through the Commons. It's appropriate given today's revelation that the Serjeant at Arms - a senior Commons official - and the Speaker himself appear to have simply doffed their hats when the police came to raid an MP's office, to seize his computer, his phones and private correspondence.
It is now clear that the police have some very serious questions to answer about the way they behaved. So too the Speaker and his officials. So too ministers who were involved in launching the inquiry.
Let us not forget, also, the question that was put again and again to David Cameron about whether he as prime minister would feel comfortable with the systematic leaking over a period of two years.
