Mr. Jimmy Carter, who was US president between 1977 and 1981, died at his home in Georgia while surrounded by his family on Sunday afternoon. Former president Joe Biden and president-elect Donald Trump have led tributes to the late Carter, a Nobel Peace Prize winner. Making a televised address from his family holiday in the US Virgin Islands, Mr. Biden said his predecessor represented "the most fundamental human values we can never let slip away".

"Jimmy Carter stands as a model for it means to live a life of meaning and purpose," he said.

"I see a man not only not our times, but for all time. We could all do well to be a little more like Jimmy Carter."

Asked if there were any lessons president-elect Donald Trump could learn from Mr. Carter, Mr. Biden answered: "Decency, decency, decency".

Carter, the longest-living former US president, is well-known for his humanitarian service after leaving Washington DC, working for Habitat for Humanity and negotiating peace deals.

It was revealed in February last year that Mr. Carter was receiving hospital care and would "spend his remaining time at home with his family".
He had decided against "additional medical intervention" following a series of brief hospital stays.

The Carter Center says there will be opportunities for the public to pay their respects in Atlanta, Georgia, and Washington DC before a private interment in his hometown Plains, while final arrangements for his state funeral are still being made.

Mr Biden says his team is "working to see to it that he is remembered appropriately."

The White House has declared 9 January a national day of mourning.

Carter's presidency will be remembered for his struggles in dealing with acute economic problems and several foreign policy challenges, including the Iran hostage crisis, which ended with the deaths of eight Americans.
