Stephen Sackur speaks to Nick Clegg, former UK Deputy Prime Minister. Elected Politicians tend to lose their grip on power and prestige with brutal speed. For Five years Nick Clegg was Britain's Deputy Prime minister, the Liberal Democrat who entered a coalition with the conservatives and gave his party its first real taste of power in generations. And then came the 2015 general election. His party was annihilated. He took much of the blame. His brand of liberal, pro-European politics now looks like badly damaged goods. Is there anyone to blame but himself?(Photo: Former leader Nick Clegg speaks at the Liberal Democrats annual conference 2015, Bournemouth, England. Credit: Matt Cardy/Getty Images)
