LONDON (Bloomberg) — UK mortgage lending fell an annual 51 percent in November, and next year borrowers will pay off more of their debt than banks lend out for the first time in at least four decades, the Council of Mortgage Lenders said. Banks loaned homeowners £14.6 billion ($22.6 billion) last month, compared with £29.9 billion a year earlier, the CML said in a statement in London yesterday. Britons may repay about £25 billion more than they borrow next year, the first negative net lending figure since records began in 1965, said the group, which represents mortgage providers.
