In the wake of the 2015 General Election defeat interim Labour Leader Harriet Harman MP commissioned an inquiry tasked with investigating why Labour lost. The inquiry was lead by Margaret Beckett MP. New Labour Leader Jeremy Corbyn MP was presented with the final report in Autumn 2015. The report has never been disseminated to party members. We call upon Jeremy Corbyn to release the Beckett report in order that members can better understand the reasons which lead to defeat last May.
