(Reuters) -British travel retailer WH Smith ( WHTPF ) lowered its full-year profit outlook for its North America division on Thursday after a review uncovered an overstatement of earnings linked to supplier income.

The company now expects its headline trading profit at the division to come in at 25 million pounds ($33.62 million), down from previous forecast of about 55 million pounds.
