In European afternoon currency trading, GBP/USD struck 1.5604, up 0.16 percent on the day.
Official data showed earlier that the euro zone economy grew 1 percent in the second quarter, well above market expectations, with Germany’s performance more than offsetting a sharp decline in Greece and slow growth in Spain and Italy.
According to forex analysis, GBP/USD was likely to touch immediate support around the low of July 30, 1.5551, and encounter resistance around Wednesday’s high, 1.586.
The pound’s gains also came ahead of a key monthly report by the University of Michigan on consumer sentiment, and data from the Census Bureau on U.S. business inventories.
Elsewhere, sterling climbed versus the yen: GBP/JPY traded at 133.93, up 0.08 percent.
