A Letter from the Queen?
GET YOURSELF A BIT OF POSTAL HISTORY!
I am not sure that you will get a direct answer from Her Majesty, I guess it depends on the subject you wish to write to her about. Most replies from her come direct from her personal secretary. But saying this I guess it depends on your luck or if you are related :-)
Anyone can write to Her Majesty at the following address:Her Majesty The Queen, Buckingham Palace, London SW1A 1AA .
Notes on the Royal web site inform us:
" If you wish to write a formal letter, you can open with 'Madam' and close the letter with the form 'I have the honour to be, Madam, Your Majesty's humble and obedient servant'. This traditional approach is by no means obligatory. You should feel free to write in whatever style you feel comfortable".
Do not forget to use a Machin for postage, SHE LIKES THE DESIGN.
