Watch: Biden’s disastrous few weeks... in 90 seconds

US President Joe Biden has announced that he will end his candidacy for re-election, saying "it is in the best interest of my party and the country".

Biden faced intense pressure from fellow Democrats to step aside after a faltering debate performance against Donald Trump in June, gaffes during the Nato summit, and looking frail after a Covid diagnosis.

He said in his statement he would address the nation on the matter next week and thanked Vice-President Kamala Harris, saying she was an "extraordinary partner".
