Trump’s tariff threat is an attempt to divide Europe and quash opposition over Greenland

Using one of his favourite weapons to win an argument, the US president underlines the unstable nature of any deal he makes

Donald Trump's threat to impose fresh tariffs on eight European countries - UK, Norway and six EU member states - is a wrecking ball to the carefully stitched deals he concluded with those countries last summer.

The two biggest voting blocs in the European parliament, the European People's Party (EPP) and the Socialists & Democrats (S&Ds), said on Saturday night the deal with the EU cannot be approved in the present circumstances.
