In a keynote speech at the UN General Assembly, the Prime Minister said Britain will continue to be the second biggest contributor to the UN, but warned that 30% of the annual £90 million funding for agencies would be ring-fenced for those showing ‘sufficient results’. She said the UN must change ‘in order to meet the challenges of the 21st century’. This echoed President Trump's earlier message that financial contributions to the UN were now under threat. Mrs May vowed Britain ‘will never let anyone destroy our way of life’, following recent terror attacks. She condemned the Assad regime's use of chemical weapons in Syria and North Korea’s controversial nuclear weapons programme, and warned Donald Trump that withdrawing from the Paris climate change treaty ranked alongside North Korea’s nuclear missile tests as a threat to global security.
