Here’s our story on Turkey’s problems:

Turkey’s unfolding economic crisis has deepened further after Donald Trump announced he is doubling US import tariffs on Turkish steel and aluminium, stoking the country’s currency freefall and rattling financial markets.

The Turkish lira plunged by more than 20% against the dollar after the president announced the move, amid a widening dispute between Washington and Ankara over the imprisonment of the US pastor Andrew Brunson.

Pressure has been applied on the country in recent days to stage an emergency interest rate rise to avert further economic damage.

Revealing an increase in US taxes on Turkish steel imports to 50% and on aluminium to 20%, the president tweeted: “Our relations with Turkey are not good at this time!”
