If anything can be a deepfake, perhaps nothing can be trusted - and politicians can take advantage of the so called "Liars' dividend" by dismissing real media as fake. In satire, deepfakes have already had a controversial impact, targeting politicians, business leaders, and celebrities. Meanwhile, convincing deepfake audio and video have the potential to create a new wave of fraud where faces, voices and bodies can be stolen. These malicious uses of deepfake technology started out targeting celebrities and people in the public eye, but have become a mainstream challenge for cyber security professionals and ordinary individuals whose images have been used without their consent. Deepfakes can be used to defame or discredit people - but on the flip side, the cry of ‘deepfake’ could undermine trust in the use of video evidence in the justice system. What can we do to protect citizens from synthetic media’s malicious uses? And might there be some positive applications for deepfakes in politics?

Ever since the 2018 mid-term elections in the US, people have been sounding the alarm that a deepfake could be used to disrupt or compromise a democratic process. These fears have not yet come to pass, but recently deepfakes of Zelensky and Putin were deployed as the Ukrainian conflict escalated. How much disruption did these deepfakes cause? How convincing were they? And are they an omen of things to come? Could deepfakes enhance disinformation campaigns that already cause significant harm? Presenter and synthetic media expert Henry Ajder unpicks the most recent deepfake video and speaks to a journalist who reported on an unusual news report which used a deepfake news presenter to attempt to spread disinformation in Mali.

What do we want the synthetic future to look like? It’s seeping into our everyday lives, but are we ready? We need a conversation about the legal, policy and ethical implications for society. Deepfakes’ murky origins are in a form of sexual image abuse that is being used against hundreds of thousands of people, most of them women. Presenter and synthetic media expert Henry Ajder speaks to journalist Sam Cole, who first reported on deepfakes in 2018. She uncovered a Reddit forum sharing pornographic videos with the faces of famous Hollywood actresses transposed on to the bodies of porn performers. Since then the technology has become much more accessible and ordinary women have become the target. Henry interviews a woman who was targeted with deepfake image abuse, and considers what we can do to protect citizens from synthetic media’s malicious uses.

Is the use of the ‘P’ word ever acceptable? Prompted by the recent allegations of racism at Yorkshire CCC by cricketer Azeem Rafiq, Rajan Datar and producer Rajeev Gupta go on a journey of personal exploration. Like many South Asians in the 1970s and 80s, Rajan was routinely called the P-word as he walked to and from school, but a new generation of young British Asians say they now claim the word and it can be used within the community as a sign of power. Rajan finds out for himself how true this is and does a context in which the use of the word is acceptable actually exist? Produced by: Rajeev Gupta

Scottish writer and broadcaster Alistair Heather is not proud of some of his past interactions with women. In a previous job as a builder’s labourer, he would watch and laugh as co-workers wolf-whistled and cat-called passing women. In the street, on trains, in cafes, bars and other public places, he would see it as his right to approach and talk to women. He knows that in behaving like that he has contributed to women and girls feeling excluded and unsafe. Now he wants to find out what he should be doing to help change the culture for the better. Alistair discusses ‘locker room talk’ with former Aston Villa youth player and Dundee United Hall of Famer Seán Dillon, challenges an old friend and explores Police Scotland’s much-praised campaign which urged men to address their attitudes to women with a hard-hitting viral video telling them: “sexual violence begins long before you think it does. Don’t be that guy". Producer Dave Howard Researcher Carys Wall Sound design Joel Cox

From allegations of cursing the king's ships, to shape-shifting into animals, or dancing with the devil, three centuries ago witch-hunting was a mania that spread right across Europe. But nowhere did it exert a greater grip than in Scotland, which had an execution rate five times higher than England's. It remains an example of just how vicious sexism and misogyny - exacerbated by superstitious beliefs and religious extremism - can be. Now campaigners are on course to win an official pardon for the estimated four thousand - mostly women - tried as witches. Leading QC Claire Mitchell, known for her prominent role in the Lockerbie appeal, is also fighting for an apology for all those accused, and for a national monument to mark the state-sanctioned atrocities she calls "the greatest miscarriage of justice in Scottish history." Claire Mitchell and co-founder Zoe Vendittozi hope that First Minister, Nicola Sturgeon will issue a formal apology. But will she? And why does it matter? Once again 'witch' is a name being levelled at women, usually in high profile cultural or political roles. It's not unusual to see figures like Hillary Clinton, Nicola Sturgeon, Professor Mary Beard, in twitter memes with green faces, stirring cauldrons and wearing pointy hats. Dani Garavelli takes a fresh look at the history and at why women were so often accused of being witches. She explores the campaign which has gained mass traction across the UK and Europe, and spawned a copy-cat campaign in Catalonia. Which power structures were being maintained then, and which ones now?

Sir Alex reflects on his upbringing in Govan, the tenements where he lived and the people who first believed in him. He reveals how his early experiences as a working man left him with values that last to this day. He tells Mike about the magic of first playing football, and reflects on the ups and downs of his playing and coaching career and their impact on what came next. Moments from the BBC Archive help Mike tell Sir Alex's story.Presented by Mike Sweeney. Produced for BBC Audio in Bristol by Camellia Sinclair. Mixed by Michael Harrison.

WH Murray was one of a pioneering group of climbers in Scotland in the 1930’s, establishing new routes in Glencoe, Ben Nevis and The Cuillin. But it was one particular mountain that he loved – and climbed – the most; the iconic Buachaillie Etive Mor at Glencoe. This was the last mountain he climbed just before leaving for war in 1941. Murray was captured in the African desert but his life was saved when he uttered the words, ‘Cold as a mountain top.’ The German officer was also a mountaineer and took him prisoner instead of shooting him on the spot. During his imprisonment in Italy and Czechoslovakia he wrote the seminal ‘Mountaineering in Scotland’ completely from memory, recalling the intimate details of climbs he undertook in the 1930’s. The book has been a talismanic text for climbers like Robert Macfarlane. He's turned to it often, particularly when the cold of the mountain top has felt very far away during recent periods of confinement. In this immersive audio voyage, Robert returns to Murray’s beloved Buachaille with 'Mountaineering in Scotland' by his side. Produced by Helen Needham in Aberdeen. Readings by Cal MacAninch. Sound design and composition by Anthony Cowie. Sound consultation and mixing by Ron McCaskill. Our mountain Guide was Richard Parker. Thanks to Robin Lloyd-Jones, WH Murray's biographer, for help with the preparation of this programme.

The Bayeux Tapestry is coming to Britain in the near future. It’s among the world’s most famous works of art, but it's also a mystery: no one knows who made it. The stitching, though, is full of clues. Abigail Youngman seeks to reveal the truth about the lives of the women who stitched it, to unpick the secrets they left in plain sight, in the margins of the tapestry. The Bayeux Tapestry records great historical events but its humanity is in the details: the little boy holding his mother's hand tightly as they flee their burning home; scenes of sexual violence; bawdy jokes at the Normans' expense. Scholarly opinion is divided, but some think it was stitched by Anglo-Saxon women who had experienced war and occupation first-hand. The main panels were probably designed by an Important Man (hence the focus on battles, on big sexy horses – surely the BMWs of their day – and political propaganda). But the margins of the tapestry may have been left to the imagination of the stitchers themselves: probably English women. This 'freehand' marginalia tell a different story, sometimes undercutting the message of the Norman conquerors in surprising ways. We can imagine the camaraderie and humour of the women sewing it, talking, about their personal tragedies, the terror they survived, the soldiers who were husbands and sons. Read this way, the Tapestry becomes a tantalising portrait of a group of women who are largely unrepresented in history, speaking to us vividly from a thousand years ago. Abigail Youngman uncovers fascinating and intimate details of these women's lives with the help of Dr Alexandra Makin, Dr Daisy Black, Dr Christopher Monk, Professor Gail Owen-Crocker and Dr Michael Lewis.
