Lehman Brothers has won its first Turkish investment banking mandate since its acquisition last week of a broking business in the country, when it became the latest foreign bank to position itself to take advantage of the European Union accession state's economic growth.

Turkish pay-TV operator Digiturk this morning launched a London sale of global depositary receipts, which could raise up to $550m (€385m), with Lehman Brother working as a bookrunner along with Credit Suisse and JP Morgan.
