In the 2016 referendum on whether Britain should leave the European Union, a stark division emerged: those with university degrees were far more likely to vote remain than those with few educational qualifications. And Britain is not the only country where such a gap exists - in the recent American presidential election, far more graduates voted for Hillary Clinton than for Donald Trump. Edward Stourton investigates the impact of this faultline on voting and politics, and asks how policy makers and wider society should respond.

How do dictators and authoritarians stay in power? James Tilley, a professor of politics at Oxford University, finds out what's in the dictators' survival guide. How do they control ordinary people and stop revolts? How do they stop rivals from taking over? And how do they manipulate apparently democratic procedures like elections - such as the notoriously fraudulent 2004 vote in Ukraine - to secure their rule? This is another chance to hear a programme, originally broadcast in 2018, that has acquired new relevance.

Electricity is crucial to modern life - and in the digital or electric vehicle age, that dependence is going to grow even more. But will we all get the power we need? Chris Bowlby discovers what life is like when power suddenly fails, and how a revolution in the way we generate electricity is posing huge political questions. This could give everyone secure, cheap power - or leave society divided between those with a bright future, and those left increasingly in the dark.

The latest round in the fight over the future of the UK armed forces is raging in the corridors of Whitehall. As politicians and military top brass argue about money, wider questions about what we want the Army, Navy and RAF to do once again top the defence agenda.

Caroline Wyatt spent many years covering defence for the BBC and has heard warnings from retired generals about chronic under-funding many times. But with army numbers already down to a level not seen since before the Napoleonic Wars, big projects like the F-35 fighter jets in trouble, and a £2bn a year black hole in the defence budget, further salami slicing seems untenable. How then to prioritise which capabilities the UK must maintain and improve?

The UK faces an intensified threat from Russia, 'hybrid' warfare where cyber attacks and political destabilisation are used alongside military force, and advances in missile technology. Post Brexit, the UK's strategic position both globally and within the European defence space is unclear. How we want to deploy our armed forces - where, with whom, and at what cost - is once again up for debate.

Poland and Hungary appear to be on paths to what the Hungarian Prime Minister Viktor Orban called "illiberal democracy". What does this mean for the European Union? Naomi Grimley hears how in Hungary a respected newspaper was shut down overnight after criticising government officials. A liberal university is fighting for its survival. In Poland, a popular singer was disinvited from a festival after speaking out against the proposed outlawing of abortion. Laws have been passed which give politicians more control over the appointment of judges. Both countries are in trouble with the European Commission. And yet, the view from Warsaw and Budapest is that their governments were democratically elected, and that they are enacting the will of their peoples - a will that may not be the same as that of Brussels, but has a popular mandate. In Hungary, Naomi is told that the country simply wants to keep its Christian identity. In Poland, the argument is that the changes of the court systems are simply an overdue updating of the judiciary after the Communist era, and that Poland is entitled to develop as its voters see fit. Could their new paths divide East and West and eventually threaten the EU itself?

Women are sexist too. Even avowed feminists are found to be unconsciously biased against women when they take 'implicit association' tests. Mary Ann Sieghart asks where these discriminatory attitudes come from and what we can do about them. Evidence for women's own sexist biases abounds. In one example, female science professors rated the application materials of ostensibly male applicants for a lab position considerably higher than the identical documentation of ostensibly female candidates, in an experiment with fictitious applicants where only the names were changed. The reasons for the pervasive bias seem to lie in the unconscious, and in how concepts, memories and associations are formed and reinforced from early childhood. We learn from our environment.. The more we are exposed to sexist attitudes, the more we become hardwired to be sexist - without realising it. So what to do? Does unconscious bias training help? Or could it make our implicit biases worse? A good start might be to tell little girls not that they look so pretty in that dress, but to ask them what games they like to play, or what they are reading. And so teach them they are valued not for how they look, but for what they do.

Donald Trump's surprise elevation to the office of president last November stunned the world and electrified the financial markets. Promises to cut red tape, bring huge infrastructure projects to life, and sort out the byzantine American tax system propelled Wall Street to record highs. It's called the Trump Bump. Yet Trump's protectionist rhetoric simultaneously created fears of a global trade war.

Martin Wolf, Chief Economic Commentator of the Financial Times, reflects on what Trump has accomplished in economic terms in the year since the election heard round the world. Financial systems are recovering from the calamities of the last decade, but that improvement was well under way before Trump took the helm of the world's largest economy. New proposals from the administration are stalled for lack of clarity, infirmity of purpose and political disarray. This doesn't mean that President Trump's decisions on everything from trade tariffs to the Federal Reserve will not send ripples around the globe in the years ahead. He's vowed to deliver tax reform, build a wall, bring jobs home and tear up trade treaties. Will these promises still be delivered? If they are, what might follow?

In 2017 it's easier than ever to express offence. The angry face icon on Facebook, a sarcasm-loaded tweet or a (comparatively) old-fashioned blog post allow us to highlight the insensitivities of others and how they make us feel - in a matter of moments. Increasingly, offence has consequences: people are told what they can and cannot wear, comedy characters are put to bed. Earlier this year, a white artist was condemned for her depiction of the body of a murdered black teenager. Those who were offended demanded that the painting be destroyed because 'white creative freedoms have been founded on the constraint of others'. It's easy to scoff. Detractors refer to those asking for a new level of cultural sensitivity as "snowflakes" and insist the offence they feel is self-indulgent. But history teaches that fringe discussions often graduate to mainstream norms. So are these new idealists setting a fresh standard for cultural sensitivity? A standard that society will eventually come to observe? Mobeen Azhar puts aside familiar critiques about the threat to free speech. Instead, he tries to understand the challenging arguments put forward by those who are pushing for new norms, and who believe that being offended will create a more culturally aware, progressive society.

These days when we talk about politicians we are more likely to discuss whether they are authentic than whether they are great orators or statesmen or women. Few of us take the time to listen to a speech or read a manifesto and when we judge politicians we more often focus on whether they seem sincere, warm or passionately committed to a cause rather than weighing up their policy programmes . We're turned off by spin and cynical about many politicians' motivations and we seek reassurance that they can really be trusted.

Professor Rosie Campbell asks how we can make judgements about a politician's authenticity. Are politicians more trustworthy if they stick to their principles without compromise? Or is authenticity about revealing our true character, warts and all? And what is better for democracy? Authentic leaders who are straight talking and stick rigidly to their ideals or leaders who are willing to negotiate behind the scenes?

Professor James Tilley finds out what we can learn about politics from the power struggles within chimpanzee groups and how our evolutionary past may affect the political decisions that we make today. Interviewing primatologists, evolutionary psychologists and political scientists, he explores the parallels between our political world and that of other primates. These include the way politicians form coalitions, how people choose leaders, loyalties to parties and even how, and when, we go to war. These similarities to other primates reflect our evolutionary heritage and the way in which stone-age human groups settled disputes internally and externally.
