Sterling surged past 1.31 versus the dollar in American trade away from September 5 lows, following earlier data from Britain and amid a lack thereof from the US today.
As of 03:34 GMT, GBP/USD rose 0.70% to 1.3105 from the opening of 1.3014, with an intraday high at 1.3116, and a low at 1.2995.
Earlier UK data showed net public borrowing rose to 4.5 billion pounds in June from 3.9 billion in May, revised from 3.4 billion, while analysts expected 3.6 billion.
UK Prime Minister Theresa May remarked earlier that the White Paper' suggestions would help progress Brexit negotiations, ruling out physical barriers between Ireland and North Ireland, while adding that EU suggestions fail to protect UK markets.
May said the EU doesn't have to go back and respond to previous Brexit proposals, but should do so with the White Paper, adding that a free trade deal as proposed by the EU is ruled out.
