Biden lauds Madeleine Albright at dignitary-packed funeral

President Joe Biden hailed Madeleine Albright at her funeral Wednesday as a diplomatic giant whose rise from child refugee to first female secretary of state represented the best of the United States.

Albright, who also served as US ambassador to the United Nations, died last month at 84.

Reflecting her status on the world stage, the televised funeral in Washington's National Cathedral was packed with more than 1,400 people and featured tributes from Biden, former president Bill Clinton who appointed Albright to secretary of state, and Hillary Clinton, who likewise served as America's top diplomat.

Among others attending were former Democratic president Barack Obama and his wife Michelle, and a Who's Who of senior Biden cabinet members, including current Secretary of State Antony Blinken, CIA Director Bill Burns, and other leaders in the military and foreign policy branches.

US House Speaker Nancy Pelosi and Biden's powerful Republican foe Mitch McConnell, who leads the opposition in the Senate, were among the congressional delegation.

Biden praised Albright as someone whose work in the aftermath of the Cold War still echoes as he marshalls the Western alliance confronting Russia over its invasion of Ukraine.

"Madeleine was a big part of the reason that NATO was still strong and galvanised as it is," Biden said, reflecting on an ongoing "severe confrontation between autocratic and democratic nations."

The veteran Democrat said Albright "turned the tide of history" through her understanding of "what American power could achieve."
