US President-elect Donald Trump has made it clear that he is not in favour of free trade.
During his election campaign he frequently spoke about the damage he believes America's trade deals have caused, claiming they have led to thousands of job losses and the destruction of the manufacturing sector.
Mr Trump has also said he will put up barriers to free trade, especially exports from China and Mexico.

Donald Trump alluded to the good relationship enjoyed by Ronald Reagan and Margaret Thatcher in his phone call with Theresa May.
Following the election of Donald Trump in the US presidential election, can the special relationship between the UK and the US continue?
