DONALD Trump says he will double steel and aluminium tariffs on imports from Turkey as its currency plummets.

The US President yesterday tweeted the Turkish lira was weak against “our very strong dollar”.

He added that “US relations with Turkey are not good at this time”.

The currency lost 20 per cent of its value in 24 hours, and has already tumbled by more than 40 per cent in the past year.

He said aluminium tariffs will rise to 20 per cent and steel 50 per cent.

Ruhsar Pekcan, Turkey’s trade minister, said the country is “deeply disappointed” by the decision made by the US leader.

Relations between the two Nato allies have soured over issues including IS and how to punish the alleged plotters of Turkey’s failed 2016 coup.

Turkey president Recep Tayyip Erdogan blasted the currency “attack” by foreign powers.

He said: “We won’t allow anyone to deter us from our goals.
