The Benson and Hedges Cup Quarter-final
Kent v Somerset
No county has won this Trophy in successive years and the holders, Somerset, despite the magnetic presence of Ian Botham , will feel better equipped to pull off the ' double ' if the giant strike bowler, Joel Garner , is pronounced fit.
Kent, beaten by Somerset in the semi-final last year and seeking revenge, have already seen their youth policy pay dividends. Both Neil Taylor and Laurie Potter have proved themselves exciting prospects for the future.

Mrs Wilberforce is one of London's nicer landladies. A little vague perhaps, but definitely not the sort of person to have a gang of desperate criminals in her house. Unfortunately, Professor Marcus and his friends are not the musical society she supposes and their plans for the little old lady are anything but harmonious. Alec Guinness plays the genial Professor Marcus with just enough menace to create a shiver between the laughs in the last of his great run of Ealing comedies.

with John Humphrys and the BBC's reporters and correspondents around the world Weatherman

A new film series. The bright lights and busy streets - the low dives and dark alleys - cops and crooks - doctors and lawyers - the good and the bad - this is the city - these are the people.

Hospital under siege. While doctors and nurses fight desperately to save two lives, they are held hostage by a young killer who threatens to kill them all ...
