I have the honour, Ma'am, to report
I wonder how Cameron would appraoch his first Tuesday Chat with Brenda after a 'Yes' vote.
"I have the honour, Ma'am, to report that I am the first Prime Minister of Your reign to cede part of Your Sovereign territory (HK was end of lease return) to foreign control. Clearly, Ma'am, this is the triumphant fulfillment of Your Government's policy, announced in Your Majesty's Gracious Speech from the Throne, blah blah"
Brenda? Amused? Shurely shome mishtake...
