Politicians and business leaders have reacted angrily to US President Donald Trump's decision to impose stinging tariffs on imports of steel and aluminium.

The European Union is taking legal action at the World Trade Organization, while Canada and Mexico - two of the biggest sources of aluminium and steel for the US - will now impose their own charges on American goods.

Trump's decision has been described as "illegal" and "unacceptable".

Is this the beginning of the end of the global trade order?
