Joe Biden is to be sworn in as the 46th US president just before 17:00 GMT in Washington. Vice-President-elect Kamala Harris will take the oath of office alongside him - the first woman to hold that position

Some 25,000 troops will guard the inauguration ceremony after a deadly riot at the Capitol earlier this month

Donald Trump will not attend his successor's inauguration - only the fourth president not to do so

He will leave the White House for the last time, bound for Florida, at around 13:00 GMT

In the final hours of his presidency Mr Trump pardoned 73 people, including his former adviser Steve Bannon
