Sterling eased slightly on Wednesday after data showing UK growth unrevised at 0.9 percent in the second quarter, and the rise in mortgage lending in August at its weakest in a year.

The number of new mortgage approvals, loans agreed but not made, fell for the third straight month in August. Sterling was trading at $1.8090 at 0837 GMT, from $1.8104 before the data releases. It was at 68.08 pence per euro , from 68.04 before the data. The GfK consumer confidence survey for September is due at 0930 GMT, forecast to show a dip to -6, after hitting an eight-month low of -5 in August. The CBI distributive trades survey for September at 1000 GMT is expected to show a positive balance of 15, from +2 in August.///
