BBC -laugh or cry?

[Kalee20]

Would many of us write Mr. Jones these days? I certainly wouldn't, preferring Mr Jones.

33 Acacia Avenue,
London,
NW9.

or

33 Acacia Avenue
London
NW9

Always the latter for me. Royal Mail agrees with me: https://personal.help.royalmail.com/app/...ressing%29

Well, I'll be jiggered!

I'd have gone for:

Mr Jones,
 33 Acacia Avenue,
  LONDON,
    Middlesex.
NW9 YXX

Having read Jeffrey's link, I'll restyle my future addressing!

And abbreviations - I tend not to use full stops after each letter.
