(Removes extraneous words in second paragraph) LONDON, Sept 29 (Reuters) - British lenders increased their mortgage lending last month after the scaling back of a tax break for homebuyers at the end of June led to a rare net repayment by borrowers in July, Bank of England data showed on Wednesday. Net mortgage lending increased by 5.293 billion pounds ($7.24 billion) in August while new mortgage approvals fell very slightly to 74,453, the BoE said. A Reuters poll of economists had pointed to a net rise of 3.7 billion pounds in mortgage borrowing in August and to 73,000 mortgage approvals during the month.
