Watch out - Rupert's about...

Rupert Murdoch alert! The chairman and chief executive of what is now the world's biggest media company, News Corporation - it has just overtaken Time Warner - has arrived in Britain and is spending the week poking about various parts of his empire. Today he hit Wapping and wandered around the editorial floor of the Sun, including a lengthy spell in editor Rebekah Wade's office. Political Cassandras will now be keeping a close and fascinated eye on the red-top's treatment of prime minister Gordon Brown. Will it soften its recent nasty stance? Tomorrow the great man will pop up in Scotland for the grand opening of News International's Eurocentral printing plant between Glasgow and Edinburgh. And Friday he will be dropping in on BSkyB's annual general meeting in London. Might he have time to visit the London office of Dow Jones while he is at it? KRM already caused quite a stir in New York by visiting the headquarters of the Wall Street Journal and taking his editor's pen to one edition. All in the nicest possible way, of course.
