The Twitter feeds of UK newspapers and their journalists could be brought under the regulation of the Press Complaints Commission, according to reports.
The Guardian claims that Twitter feeds are expected to be brought under the press watchdog's remit later this year.
According to that report the PCC considers some postings on Twitter as part of a 'newspaper's editorial product', so they should be bound by the same code of practice that applies to newspapers and their websites.
As it stands the PCC cannot rebuke a newspaper, or a journalist, for messages they put on Twitter.
The challenge for the PCC will be to determine how exactly it should apply its code to social media when many journalists mix personal and professional messages on their Twitter feeds.
