US President Joe Biden signs climate, tax and health bill into law

US President Joe Biden has signed a $700bn (£579bn) bill that aims to fight climate change and healthcare costs while raising taxes mainly on the rich.

The act includes measures to make good on decades of congressional promises to curb the price of prescription drugs.

The final version is more modest in scope than the $3.5tn package first envisaged by Democrats.

A flagship of Mr Biden's agenda, the bill could provide a boost ahead of the mid-term elections.
