Pulitzer prize winning journalist and author Seymour Hersh in conversation with the Guardian's deputy Editor Paul Johnson.

In 2011, an elite group of US Navy Seals stormed an enclosure in the Pakistani city of Abbottabad and killed Osama bin Laden.The news did much to boost President Obama's first term and played a major part in his re-election victory the following year. Four years on, the publication of Hersh's controversial London Review of Books essay argues the story of that night, was incomplete, or worse, a lie.How realistic is it that Pakistani authorities didn't know bin Laden was living in a compound next to a military academy or have any knowledge of the US military operation?

Join us as we hear Hersh's case - which includes quotes from ex-CIA and ISI sources - and also discuss with him his latest book investigating the level of US involvement in the Syrian conflict.
