Two of Britain’s most active left MPs paid tribute to a “superb” new book from Establishment-challenging author Andrew Fisher in Westminster on Wednesday night.

Labour MPs John McDonnell and Jeremy Corbyn hailed The Failed Experiment And How To Build A Future That Works, which exposes the follies leading to the 2008 crash — and suggests ways forward.

Mr McDonnell told a launch event: “This book is an excellent piece of work. It will be used by all of us in our campaigning.”
