Nigeria: Bribery charges filed against Dick Cheney

Nigeria has filed charges against former US Vice-President Dick Cheney over a scandal involving a former subsidiary of Halliburton energy firm. The case, brought by the country's anti-corruption agency, centres on engineering firm KBR, which admitted bribing officials. Cheney's lawyer has called the allegations 'entirely baseless'. Cheney was Halliburton's chief executive before becoming vice-president to George W Bush in 2001.
