Can anyone confirm for me the correct way to sign off a formal letter. I always thought that Dear Sir letters (where you don't know the name) ended with Yours Faithfully and Dear Mr Smith (where you do know the name)letters ended with Yours sincerely. However, I've just received a letter from the British Council in Brasilia with the endings the other way around ie. starting Dear 'Albert' and ending Yours faithfully. I'm confused - which is right? Now I don't know how to reply.
