There has been a dramatic fall in the value of the pound as traders react to the latest results from the UK's referendum on EU membership.
At one stage it hit $1.3477 - a low not seen since 1985.
Before the results started to come in the pound rose as high as $1.50, as traders bet on a Remain victory.
But following early strong Leave votes in north-east England it tumbled to $1.43 and then took another dive after 03:00 BST as Leave maintained its lead.
Currency traders say these moves are more extreme than those seen during the financial crisis of 2008.
