The number one Irish Times bestseller. In 1970, Taoiseach Jack Lynch accused two cabinet ministers, Charles Haughey and Neil Blaney, of smuggling arms to the IRA in Northern Ireland. The criminal prosecution that followed was a cause celebre at the time. All the accused were acquitted, but it generated a political crisis that would be one of the major events of modern Irish history.

In the fifty years since, myth and controversy has surrounded the trial and its aftermath. Michael Heney has unearthed astonishing new evidence, raising serious questions about Lynch and his relationship with Haughey. The Arms Crisis of 1970 is the first comprehensive investigation into the arms trial prosecution, and how the jury came to their verdict of acquittal.
