The dollar bounced back to a one-week high on Friday following upbeat U.S. growth figures, while Britain's pound slipped after a poll showed a narrowing lead for the ruling Conservatives before elections next month.
The dollar index, which tracks the greenback against six major rivals, was up 0.19 percent to 97.43, after rising to a high of 97.512, its strongest since May 19.
Economic growth in the U.S. slowed less than initially predicted in the first quarter. Gross domestic product increased at a 1.2 percent annual rate instead of the 0.7 percent pace reported last month.
The greenback was initially under pressure earlier last week after minutes of the Federal Reserve's most recent meeting showed policymakers agreed they should hold off on raising interest rates until it was clear a recent U.S. economic slowdown was temporary.
USD/JPY fell 0.52 percent to close the week at 111.24 after paring earlier losses and EUR/USD slipped to a 1-week low of 1.1161.
Sterling plunged about one percent against the dollar to a 1-month low of 1.2791 after a YouGov poll published on Thursday showed British Prime Minister Theresa May's lead narrowing to just 5 percentage points over the Labour opposition less than two weeks before a general election.
Meanwhile, the Canadian dollar and its New Zealand counterpart recovered ground against the greenback after slipping sharply on Thursday on weakness in commodities, including crude oil.
