" Yeah, right. And your piece is over two years old, by the way. Perhaps you could explain why, in spite of a terrible election result for the Tories, terrible divisions in the ruling party and shocking and ongoing stasis in the brexit negotiations, the pound hasn't wobbled very much at all in the last four or five months."

Simples: The world knows that the economy under the mighty conservatives is in safe hands, despite bickering.

Should you wish to see extreme instability and a crash just put clot corbyn at the helm. Even he knows he is a walking disaster. Why else wargame a massive collapse of the pound should the country ever be daft enough to give him a sniff of power.
Good luck trying to find a pundit that can counter the argument against corbyn.
