Watchdog to launch inquiry into misuse of data in politics

Investigation follows revelations of digital firm's involvement in Brexit

The UK's privacy watchdog is launching an inquiry into how voters' personal data is being captured and exploited in political campaigns, cited as a key factor in both the Brexit and Trump victories last year.

The intervention by the Information Commissioner's Office (ICO) follows revelations in last week's Observer that a technology company part-owned by a US billionaire played a key role in the campaign to persuade Britons to vote to leave the European Union.
