US will impose 35% tariffs on Canadian imports, Trump says in letter

New levies, apart from the 25% on auto parts and 50% on steel and aluminium, will come into effect on 1 August

Donald Trump has said the US will impose a 35% tariff on imports from Canada from the beginning of August, and threatened to impose blanket tariffs of 15% or 20% on most other trading partners.

The US president sent a letter to Canada late on Thursday, after an interview in which he warned EU nations to expect a tariff announcement today or tomorrow".
