Joe Biden's career in pictures: From one of the US's youngest ...
After intense pressure from his party, US President Joe Biden has chosen not to contest the presidential election later this year.
It makes him the first sitting American president since Lyndon B Johnson to choose not to run for re-election.
Mr Biden has had a long career in politics, having spent more than half a century in public life.
He won his first elected position in 1970, becoming a councillor on the New Castle County Council in the state of Delaware.
He then spent about 36 years in the US Senate, which saw him leave his mark on some of the biggest political moments in America over the past few decades.
He ran for president unsuccessfully on two occasions, in 1988 and 2008, before he was chosen to be the vice-presidential nominee on Barack Obama's 2008 presidential ticket.
After choosing not to run for president in 2016 following the death of his son Beau, he ran in 2020 and defeated incumbent president Donald Trump, leading to his return to the White House for what is now set to be a single term.
