The past day has been an extraordinary one in the history of modern America.

Firstly, the Democrats secured a majority in both houses of Congress.

Secondly, Congress certified Joe Biden’s election victory - although many Republicans challenged the votes of some states.

Thirdly, while the political debates were underway, pro-Trump supporters stormed the Capitol and four people died.

David Aaronovitch is joined by an expert panel of guests to examine what just happened and what does this mean for the United States, its institutions and its politics.
