Who are some of the key figures nominated to be in Joe Biden's cabinet?

Joe Biden has nominated one of the more diverse cabinets in US history with some familiar faces from the previous Obama administration.
Many of the nominees for the President-elect's incoming government will have to be confirmed by a majority vote in the US Senate, which may be easier for Democrats after two spectacular wins in Georgia.
Several hearings are already scheduled for next week when Biden is set to become the 46th president of the United States.
Here's a look at some of the key figures who are nominated to work alongside the incoming US president and Vice President-elect Kamala Harris.
Secretary of State: Antony Blinken
Antony Blinken will be the US' top diplomat in the Biden administration, directing the country's foreign relations. This means he will be a crucial figure in the administration and is likely to have contact with European leaders.
Blinken is the former Deputy Secretary of State in the Obama administration and has advised Biden since 2002 on foreign policy.
Secretary of Defence: Lloyd Austin
Lloyd Austin will be the first African American to hold the post of US defence secretary, putting him in charge of the US government's largest and most expensive department.

He will become the chief lawyer of the federal government and head of the Justice Department under Biden.
