(Telecompaper) Telefonica has once again begun working on the planned IPO of its infrastructure division Telxius now that the impact of Brexit on markets appears to have died down, according to unnamed sources cited by Bloomberg. Banks working on the IPO could start meetings with investors as early as next week, allowing Telefonica to list the company on the Madrid stock exchange by the end of September, said the sources. In June the company said it was delaying its already well advanced plans to list its infrastructure unit due to market instability following the UK vote to leave the EU.
