As someone that served as a liaison with many UK army and airforce units deployed in many countries was accustom to use UK postal services and was very happy with the result. Well, yes up to 2002 when something happened to them and services offered began deteriorate..
Now are amongst the worsed in the old continent (yes avoid mention EU here intentionally ).
Today the UK postal services are bought by the German ones , will this make them back the best available?
A and one more question why after the you've sold London stock exchange and agreed to a German CEO now you've sold postal too? Are you in or out of the EU?
