Welcome to the Post-Truth era- a time in which the art of the lie is shaking the very foundations of democracy and the world as we know it. The Brexit vote; Donald Trump's victory; the rejection of climate change science; the vilification of immigrants; all have been based on the power to evoke feelings and not facts. So what does it all mean and how can we champion truth in in a time of lies and `alternative facts'?

In this eye-opening and timely book, Post-Truth is distinguished from a long tradition of political lies, exaggeration and spin. What is new is not the mendacity of politicians but the public's response to it and the ability of new technologies and social media to manipulate, polarise and entrench opinion. Where trust has evaporated, conspiracy theories thrive, the authority of the media wilt and emotions matter more than facts .

Now, one of the UK's most respected political journalists, Matthew d'Ancona investigates how we got here, why quiet resignation is not an option and how we can and must fight back.
