LONDON (AFP) - United States investment bank JPMorgan Chase on Friday (June 24) warned that it could relocate UK jobs abroad following Britain's vote to leave the European Union.

"In the months ahead... we may need to make changes to our European legal entity structure and the location of some roles," said a staff memo obtained by Agence France-Presse.

JPMorgan employs 16,000 people in Britain, while chairman and chief executive Jamie Dimon previously said up to 4,000 jobs could move out of the UK.
