The Attorney General is set to start tweeting advice to prevent social media users from committing contempt of court, an offence that can be punished with a prison sentence.
In a statement issued today, Dominic Grieve said that that the advice was "designed to help facilitate commentary in a lawful way".
Grieve, who pointed to one case that collapsed due to tweets by a jury member, added:
"In days gone by, it was only the mainstream media that had the opportunity to bring information relating to a court case to such a large group of people that it could put a court case at risk. That is no longer the case, and is why I have decided to publish the advisories that I have previously only issued to the media."
