Tokyo - The pound suffered a "flash crash" on Friday morning in its biggest drop since Britain's Brexit vote in June, with warnings of further volatility ahead for the beleaguered currency as Asian stock markets retreated.
In early Asian trade sterling plunged more than 6% against the dollar, with experts blaming the sell-off on technical issues or human error.
But some market-watchers said the event illustrated the fragility of the British unit since the country's shock referendum vote on June 23 to leave the European Union.
