James Murdoch is to step down as chairman of UK satellite broadcaster BSkyB, but will remain on the board. He is the son of News Corporation founder Rupert, whose company had to drop its bid for BSkyB after the phone-hacking scandal. In February, James Murdoch stepped down as chairman of News International, which publishes the Sun and the Times in the UK. He said then he had moved to New York to work on News Corp's pay-TV business. News Corp owns almost 40% of BSkyB and had wanted to buy the whole of the firm. But it withdrew its bid as political pressure mounted due to allegations of improper conduct at News International's News of the World Sunday title, which was shut down last July. Sources told Robert Peston, the BBC's business editor, that it was James Murdoch's decision to leave and he did so in an attempt to pre-empt further criticism as investigations continue into phone hacking. James Murdoch has repeatedly denied knowing about phone hacking at the News of the World. Nicholas Ferguson will take over as chairman.
