In a powerful and provocative authored film, Trevor Phillips investigates the liberal urge to protect minorities from offence by gagging so-called populists and concludes that for liberals it's backfired. The backlash has stirred the Trump-Farage-led revolt - and even alienated the minorities whom liberals claim to champion. From the sacking of a Nobel scientist for a politically incorrect joke to the banning of sombreros on campus, the liberal elite's unwritten rules about what you can or can't say risk becoming not only ridiculous but self-defeating. For Trevor, the acid test of a democracy is whether it truly encourages the airing of different opinions whatever they might be - a test that Britain seems in danger of failing.

This programme goes behind the scenes of one of the hardest exams in the world; the one that all the black cab drivers in the capital must take: The Knowledge of London.

The film will show these images together in stunning time-lapse sequences to reveal how we are reshaping our world, for better and for worse - from the sprawling megacities of China to vast desert farms in the Middle East, and the melting snow cap of Kilimanjaro, to giant solar arrays in Nevada.d worse

In this authored historical investigation, historian Tom Holland traces the origins of Isis's extreme violence, which it claims is justified by the tenets and scriptures of Islam. Travelling from Paris to Istanbul, and from Sinjar to Cairo, he examines the roots of Isis's interpretation of notions such as jihad and caliphate; he investigates why Isis have persecuted different religious minorities in different ways; and he asks whether the group's ideology is in part a reaction to a westernisation of Islam that ultimately dates back to the time of Napoleon. Holland questions the assertion - much repeated by western leaders - that Isis has nothing to do with Islam. He examines the origins of the group's beliefs, which he traces back to the very origins of Islam.

To mark the 50th anniversary of the partial decriminalisation of homosexuality in England and Wales, Convicted for Love tells the dramatic and emotional story of four gay men who fell foul of Britain's homophobic laws. The government's 2017 Turing's Law promises a pardon and an apology for men like these, who were hounded for their homosexuality. But this documentary reveals that, for many of them, the injustice continues. Fifty years ago, the 1967 Sexual Offences Act was hailed as a great step forward for gay rights. It gave the impression that it made all homosexuality legal for men. It didn't. It only legalised sex in England and Wales between two men over the age of 21 - in private. It also didn't mark the end of discrimination against gay men. Many aspects of their everyday lives remained illegal. In the following decades these men have had a long, hard struggle for their rights. Over 15,000 men were unfairly convicted of homosexual offences.
