The beleaguered British pound has plummeted briefly to a fresh 31-year low amid intensifying concerns about Britain's exit from the European Union.
The pound tumbled nearly 6 per cent in early Asian trading on Friday, falling as low as $US1.1789, according to FactSet data.
The British currency, which had been trading at around $1.26 the day before, recovered minutes later. It was recently trading around $1.24.

Some attributed it to a trader's "fat finger'' mistake or a rogue automated trading algorithm.
