The play runs April 19 through May 19. According to The New York Times, Richard Norton-Taylor, a journalist for The Guardian, will adapt the play from upcoming testimony from 20 experts on the subject, including members of Parliament, diplomats, international lawyers, civil servants, United Nations officials, policy advisors, intelligence experts and journalists.

The experts will be questioned by the British barristers Philippe Sands (for the prosecution) and Julian Knowles (defense) in the next month.

Nicolas Kent, Tricycle's artistic director, will direct. Kent told the Times that creators might choose to have the audience vote on a verdict at the end of the play.

The Tricycle is known for such politically-conscious work as Guantánamo: Honor Bound to Defend Freedom — the documentary play about the United States' political prisoners in Guantánamo — which went up in 2004 and transferred to the West End and the Culture Project in Manhattan.

Norton-Taylor's previous documentary-style plays include Half The Picture, The Colour of Justice, Justifying War and Bloody Sunday — Scenes From The Saville Inquiry.

The Tricycle is currently running the European premiere of by David Kramer's musical Spice Drum Beat — Ghoema. Before the Blair play, the theatre will stage the world premiere of Tamsin Oglesby's The War Next Door and a production of Harold Pinter's The Caretaker.
