David Hockney
In this new series, six major contemporary painters create pictures that exist only on your television set at home. For the first time, artists like Howard Hodgkin, Sir Sidney Nolan , Richard Hamilton and tonight, David Hockney , are confronted with the extraordinary Quantel
Paintbox, a computer that offers an electronic, and infinitely adaptable, palette and brush, and that stores and recalls each step of the process of picture-making.
In a day-long session,
David Hockney paints directly on to the television screen - studies of his London studio, and a portrait of Francis Bacon - and as the day progresses he describes his reactions to this challenging new technology. 'I've no doubt it's a new medium. You're drawing with light on glass, and it gives a richness of colour that even paint can't give. It's a picture that doesn't exist in any other form.'

With Duncan Campbell.
Membership of one of Britain's tiniest 'trade unions' is restricted to those at the very top of the law and order business. The Association of Chief Police Officers represents 280 of our most senior policemen. Yet its influence on Government policy has been profound.
Hardly anyone had heard of ACPO until it was plunged into controversy in 1984, at the heart of the miners' strike. Then the Association was in the public eye, organising national coordination between police forces. Even now, almost all of its deliberations, decisions and documents are confidential. Who truly decides national policy in most fields of law and order? Have ACPO's leaders been open enough on vital matters of policing policy - like public order, intelligence gathering in the community or policing industrial disputes? Duncan Campbell turns detective to report on the outlook, accountability and hidden influence of the Chief Constables' club.
