President Donald Trump A quarter of Britons believe Donald Trump presents the greatest threat to the UK’s national interests, according to a new poll.The Good Growth Foundation think-tank found that 24% of the British public think the unpredictable US president is more dangerous than terrorist organisations (22%).Only Russia beat Trump in the poll, with 34% of Brits seeing Moscow as the largest risk to the UK.That’s a blow to Downing Street, considering Trump is expected to confirm a long-awaited economic trade deal with Britain this afternoon. Labour is hoping any such agreement would grant the UK some exemptions to Trump’s sweeping 10% tariffs on foreign imports and his 25% levy on cars and aluminium.But the Good Growth Foundation found almost half of Brits (47%) think Trump will also worsen the UK’s economy.A
