On 20 January 2021, Joe Biden will – pending legal challenges – be inaugurated as the 46th US president.

He’s expected to get down to work immediately in trying to unwind key parts of Donald Trump’s agenda. Here’s some of what we know:

Climate: He will tell the UN that America will again join the Paris Agreement that Donald Trump left.

Only a month’s notice is needed and the US should be back in the global pact to fight climate change that commits nations to reducing emissions.

Covid: As we just reported, Biden has pledged to set up a Pandemic Testing Board to “produce and distribute tens of millions of tests”.

He also wants to set up a nationwide contact-tracing programme and call on governors to impose mask-wearing mandates..

Immigration and borders: He has vowed to end any separation of migrant families at the southern border and to immediately rescind the controversial travel ban that targets several Muslim-majority countries
