The sweeping plan, which tops Donald Trump's $4.8tn proposal last year, promises infrastructure upgrades and an expanded social safety net.

The proposal will be given to Congress and needs approval to be implemented.

If passed, it will bring the US to spending levels not seen since World War Two.

The budget provides a picture of a president's priorities. In this case, Mr Biden's proposal reflects his vision of an expanded government with spending levels to match.

Mr Biden said that his budget "invests directly in the American people and will strengthen our nation's economy and improve our long-run fiscal health".

President Biden's plans include more money for roads, bridges, broadband internet and water pipes.

The surge of new spending would also allocate $200bn over 10 years to provide free pre-school to all three and four-year-olds and $109bn to offer two years of free community college to all Americans.
