The philosopher Onora O'Neill criticises the standard of public debate on both sides of the European Union decision and asks how this democratic deficit can be repaired. "The disarray that we now witness, and the retractions, revelations and recriminations that spill out on a daily basis, show that large parts of each campaign failed to communicate with the public, did not offer adequate or honest accounts of the alternatives, and did not provide the basic means for voters to judge the real options, the real opportunities or the real risks." This is the first of a series of special editions of Radio 4's long-running essay programme, A Point of View, in which five of Britain's leading thinkers give their own very personal view of "Brexit" - what the vote tells us about the country we are, and are likely to become.
