An increase in the use of social media to spread details of events covered by privacy laws is affecting what newspapers can and cannot print.

While people at home may not always use their own ink cartridges to print off the latest tweets relating to any of the celebrity news of the day, newspaper printers are not able to produce such details because of England's privacy laws.

The prime minister, David Cameron, has today commented on the matter, suggesting that social media growth has left the press at a disadvantage when it comes to being able to print details in public interest cases.

His comments follow the widespread naming of people who have taken out superinjunctions to protect their names after details of affairs have been revealed. However, many Twitter users have quickly spread the names of the celebrities involved in the cases, even though the press are not able to do so.
