Dick Cheney, the former Republican vice-president who championed US wars in Afghanistan and Iraq after the September 11 attacks and then became a fierce critic of Donald Trump, has died aged 84, according to a statement from his family.
Cheney served as vice-president during the presidency of George W Bush between 2001 and 2009, capping a political career that included tenures as defence secretary under George HW Bush and White House chief of staff under Gerald Ford.
He was best known for his hawkish views on foreign policy and the use of American military power, including a pivotal role in advising George W Bush to order the invasion of Iraq in 2003. That presidential decision plunged America into a lengthy and costly Middle Eastern conflict that many Republicans and Democrats would later judge to have been a mistake.
