The British pound was unchanged on Friday at the end of its best week since January, as investors waited for next week's parliamentary vote on Prime Minister Theresa May's deal to exit the European Union.
Sterling has rallied this week - it is up 1.7 percent against the dollar - after British lawmakers voted against leaving the EU without a deal and backed a delay to the March 29 exit date.
The vote against a no-deal Brexit was non-binding, but investors believe Britain will now avert a disorderly Brexit that would severely damage its economy.
May has said she will hold another vote next week on her deal, although lawmakers have already rejected it twice. She hopes to use the threat of a longer delay to Brexit to persuade eurosceptics in her party to back her.
