Former US President George W Bush has led tributes to Dick Cheney, saying his death is "a loss to the nation and a sorrow to his friends".
Cheney died from complications of pneumonia and cardiac and vascular disease on Monday night at the age of 84, his family said in a statement.
He became one of the most powerful US vice-presidents in history under Bush, and leaves behind a controversial legacy as a key architect of the "war on terror", and an early advocate of the 2003 invasion of Iraq.
"History will remember him as among the finest public servants of his generation," Bush said in a statement.
