London | Prime Minister Scott Morrison has launched an attack on Donald Trump's trade wars, stopping just short of naming the US President as he warned of a "zero-sum mindset" and a "transactional approach" that was putting living standards and prosperity at risk.

Speaking to a business audience on Tuesday in London, where he is visiting for World War II D-Day commemorations alongside Mr Trump, Mr Morrison said countries' relationships with each other were about their history, values and connections, and this amounted to "more than just the sum of their deals".
