What spot in Britain speak with an accent most closely resembling typical American Midwest Newscaster accent?

Question

By Newscaster accent I mean the accent concidered "General American" and is used by most newscasters. It is sometimes concidered "accentless" of course everything is an accent but "accentless" means its not New Englander, not Southern, not Western accent. Rather normal American accent. My question is where in the UK (britain) do they speak almost the same. I've heard some from Yorkshire that sound pretty close also a man from Cornwall sounded rather American.

I want to make it clear that YES most British accents do not sound American. Yet it is officially recognized that Britain has more English accents then the entire world of English accents. Somf of those British accents are more similar to American Standard. That is my question. Which Brit UK accent sounds most like American. I know some areas of Yorkshire county sound closer to American.

Answer 1

To a brit none of these could pass for american

to us the american accent, although generally easily understandable, sounds distinctly american/canadian (they sound so similar to us to each other) and not british at all

Answer 2

Nowhere.
