The pound fell against the dollar and euro on Thursday, on track to end its longest winning streak against the U.S. currency in 2-1/2 years, driven by dollar moves and Brexit-related concerns.

The pound had risen 3.9% against the dollar in 10 consecutive days of gains starting on May 28 - its longest winning streak since January 2018.

But this trajectory looked set to end on Thursday, as the pound changed course and fell back below $1.27, also falling to the key 90 pence level versus the euro.

Versus the dollar, the pound fell as much as 0.9% on the day to $1.2634 at 13:49 GMT, having risen to a three-month high above $1.28 on Wednesday By 15:00 GMT it was down 0.8% at $1.2643.

Against the euro, the pound fell overnight, steadied in early London trading, then fell further, reaching the key 90 pence per euro level at 14:46 GMT, down around 0.9% on the day.
