Over a year after the Leveson report came out, regulation of the British press is still a question of intense debate. Meanwhile, the NSA/Snowden revelations – and the related detention of David Miranda (supported recently by British courts) – open up core questions of how investigative and public interest journalism can function in a world of mass surveillance. In the US, while Guardian editor-in-chief Alan Rusbridger rightly praises the first amendments, Obama himself has a growing reputation as a president who has pursued sources and journalists through the courts.

Join us on a Google Hangout with Guardian Digital journalist, James Ball (now based in New York) and LA Times London correspondent, Henry Chu, hosted by our Editor, Online and News, Sean Gallagher for a lively debate around the media freedom on either side of the Atlantic.

The recording will be broadcast live via Index’s Google+ and YouTube accounts from 10am (EST)/ 2pm (GMT) on Wednesday 26th March. Get involved in the discussion on our Twitter feed and website. Visit the Google+ page here and the YouTube page here.
