In May 2010, Cable declared his resignation as Deputy Leader to dedicate more time to his Cabinet role as Business Secretary. His responsibilities and authority were somewhat reduced when it was revealed in December 2010 that he had boasted to "Daily Telegraph" reporters posing as constituents of his "nuclear option" to bring the government down by his resignation. Still worse, he claimed to the reporters that he had "declared war" on Rupert Murdoch of News Corporation despite having the responsibility to impartially arbitrate on the News Corporation bid to acquire the remaining 60.9% of BSkyB it did not already own. Amid cries for his resignation or sacking, all his responsibilities concerning the bid were removed. Cable did not resign.
