Yesterday, the pound slumped below $1.26 to the lowest level since April 2017 after the prime minister said she cancelled the vote on her Brexit plan rather than see it rejected by a “significant margin”. Sterling was worth $1.2563 and €1.1062 late on Monday, and at time of writing its fortunes are little changed.

Nothing to do with Epicurus, but everything to do with the international view of Brexit and its effect on the UK. Not just shooting yourself in the foot – using a machine gun. Good for exports, though.
