Chris Bowlby visits one of the homes of German car culture and a populist stronghold, Zwickau, to see how motoring is rising up the German agenda. Is Zwickau a foretaste of something affecting all of Germany – a car-loving, car-manufacturing powerhouse in the past, now wondering anxiously what the future holds against the emergence of Chinese electric cars. And less than a hundred miles from Zwickau, just across the border in the Czech Republic, a new coalition government has recently taken power, including ministers from a populist party called Motorists for Themselves – muscular defenders of the old petrol car.

*** This programme contains scenes of a sexual nature and discussion of sexual assault, including child sex abuse *** Neha Vyaso is one of the most successful intimacy co-ordinators in Bollywood. She has worked with some of Bollywood's biggest names, including actors Tiger Shroff, Deepika Padukone and Konkona Sen Sharma, and directors like Hansal Mehta.

We join her in a workshop with two actors, who are getting comfortable with each other, their roles, and the techniques of consent and conversation that Neha is an advocate of. As they work on the choreography of their sex scene, Neha articulates how it’s a fine balance between the demands of a script, a director's vision, a character's emotional arc, and what an actor can consent to.

When war broke out in 2020 between Ethiopia's federal government and the the Tigray region of the country, many women in Tigray joined the armed forces, in part to avoid sexual violence, as reports of women being assaulted by soldiers started to appear.
