Budvar10:
In my opinion this is too much of punctuation. Or am I wrong and it is correct? Can somebody with native English and good knowledge of grammar, write it correctly?
I am a native English speaker but I won't pretend to be a grammar expert. I would write that sentence like this as two separate sentences. In general shorter is better.
If you don't have some kind of rules then things can be a bit difficult to follow and it becomes harder to communicate. Also, I have always thought (that) the English in England was a bit hard to understand.
