LONDON (AFP) - Rupert Murdoch was heading to London to take charge of dealing with a phone-hacking scandal that has felled his News of the World tabloid, as journalists Saturday prepared the paper's final edition. The News Corp. chief was due to arrive in Britain on Sunday, a company source said, as the sensationalist tabloid that has been in circulation for 168 years hits news stands for the last time. Murdoch has been keen to limit the fallout from the crisis which has cast a shadow over his bid to take full control of satellite broadcaster BSkyB, on which the government is due to decide soon. The opposition Labour party meanwhile ratcheted up pressure on Prime Minister David Cameron, a day after one of his former aides was arrested over the scandal, demanding the establishment of an inquiry be speeded up. Murdoch's arrival comes as about 200 staff at the News of the World face an uncertain future as the paper closes its doors. News of the World journalists said emotions were running high as the paper prepared to go to print for the last time. Editor Colin Myler said it was a "very difficult day for us all", in a personal e-mail to staff. "It's not where we want to be and it's not where we deserve to be," he wrote. "But I know we will produce a paper to be proud of."
