The British pound paused for breath on Friday after the UK parliament voted overwhelmingly to seek a delay in Britain's exit from the European Union while the yen looked to the Bank of Japan's guidance on its policy later in the day.
Sterling fetched $1.3253, having slipped further from Wednesday's nine-month high of $1.3380, with its fall of 0.76 percent on Thursday.
Against the euro, the pound retreated to 85.25 pence from Wednesday's 22-month peak at 84.725.
British lawmakers approved a motion setting out the option to ask the EU for a short delay if parliament can agree on a Brexit deal by March 20, or a longer delay if no deal can be agreed in time.
The pound was mostly steady after the motion was passed late on Thursday.
