Theresa May's "Muddled Speaking" causes the pound to fall

On Sunday (8th January) Theresa May was interviewd by Sophy Ridge.

Theresa May was, of course, asked many questions about Brexit.

On the basis of Mrs. May's "muddled speaking", the pound fell.

See, for example, Pound falls on May's Brexit comments.

If the pound falls on a hint of what I call "Trainwreck Brexit", how much more economic damage might it do if it becomes clear that Theresa May is headed towards Trainwreck Brexit?
