Former International Development Secretary Clare Short MP and Michael Codner, Director Military Service at RUSI (Royal United Services Institute), join Stephen Tindale, Executive Director of Greenpeace UK (centre), for the Greenpeace debate on the future of UK nuclear weapons, taking place at the annual Hay Festival. The debate, entitled 'War and Peace', was organised to highlight the conspicuous lack of parliamentary discussion about a replacement for the existing Trident nuclear weapons system.
