LONDON, July 29 - Sterling built fresh gains against the dollar on Tuesday, setting a two-week high as investors drifted back to the UK after a political row last week sent many players scurrying away. Consumer borrowing data could provide a further boost to the British currency later in the day if it shows another hefty rise in debt that would signal robust consumer spending and cloud any expectations of further monetary easing. "We have seen a lot of selling pressure last week, because of the political risk premium," said Hans-Guenter Redeker, chief foreign exchange strategist at BNP Paribas in London. "But the economy is not looking that bad, and data, including retail sales, has been coming in much stronger. Consumer borrowing data is also important since consumers have been an important engine of growth." By 0830 GMT, sterling was up 0.17 percent on the day against the dollar, slightly below a two-week peak of $1.6310 set earlier. Analysts said $1.6320 was a strong resistance level for now. Against the euro, sterling was 0.10 percent down at 70.68 pence. Consumer borrowing is expected to have risen 1.6 billion sterling ($2.60 billion) in June, versus May's 1.7 billion increase. The data is due out at 0830 GMT. Earlier this month, some members of the Bank of England's Monetary Policy Committee warned that the rate of growth of consumer credit was unsustainably high and therefore worrisome. However, the MPC still voted to cut rates at the start of July, because of weakness in the global economy and stronger sterling. Earlier on Tuesday, data from the Nationwide Building Society showed house prices rising one percent in July, versus June's 0.9-percent increase. It showed some cooling in the fiery housing sector on the annual basis. Meanwhile, a row between top UK government officials and the BBC over the apparent suicide of British arms expert David Kelly, who was at the centre of a debate over Britain's participation in war against Iraq, slipped off newspapers' front pages. A judicial inquiry into Kelly's death will begin on Friday.
