Nine stories set in a time-share flat. 8: For Business Reasons by GEORGE PENSOTTI

The flat has been lent by a business firm to a prospective Dutch client and his wife. Philip and his wife, Marcia, plan to be on hand to tie up the business deal over the weekend-but they don't bargain for the real 'business' test they are subjected to when they encounter Erik and Ingrid.

Bernard Levin in conversation with Sir Clive Sinclair
'Within the not-too-distant future, we may not be the most intelligent species on earth.'
These are the words, not of a science-fiction writer, but SIR CLIVE SINCLAIR , whose list of technical advancements to date make his assertions hard to ignore. He introduced the first pocket calculator, the first digital watch, the first flat-screen pocket TV and helped raise the level of computer literacy in Britain with his range of affordable microcomputers.
In this conversation he shares his view of the present day and his extraordinary vision of the future.

The forest and beaches of the Nordic countries are recalled by the members of the Danish Royal Ballet as they dance to the choreography of Flemming Flindt and specially composed music by Svend S. Schultz.

This powerful and beautiful film launches the first ever British television season of New Zealand films.
A remote settlement in the 1880s. An English emigrant joins the battlefield to photograph the war between colonial soldiers and native Maori tribes. His pictures present a grimly realistic portrait of the fighting, which the authorities try to suppress. They employ his brother to present a flattering image of the Maoris' pitiful life. The commission inevitably causes friction between the brothers, reflecting the political division within the country. Shot on stunning locations, this film-with its complex interweaving of social and personal issues - enjoyed both critical and commercial success on its release in Britain last year.

The 1984 Formula One World Championship Detroit Grand Prix
Motown's bumpy street circuit, with its tight corners and short fast straights, might give a little hope to the non-turbo cars. Remember a Tyrrell won the race here last year-so don't write off the British driver MARTIN BRUNDLE.
The fall of the chequered flag today marks the half-way stage of the 1984 season. If the Surrey-based team of McLaren are even further out in front tonight in both the Drivers' and the Constructors' Championships than they were when they left Europe, it will be difficult to bet against both titles going to Woking.
