Former Australian foreign minister Gareth Evans has launched a blistering attack on US President Donald Trump.
Mr Evans has lambasted Mr Trump as "the most ill-informed, ethically challenged and psychologically ill-equipped" president in US history.
"Personally driven by instinct and impulse, unhampered by knowledge or judgment, he has led an administration, acting so far manifestly on the basis of postures and not of policies," Mr Evans told the National Press Club in Canberra on Thursday.
