Mr Sanders may be correct about that as a new Gallup Poll suggested median approval of US leadership was just 30 per cent, down from 48 per cent.

The previous historical low was 34 per cent during the administration of President George W Bush.

The perception of Mr Trump sharply declined compared to that of Mr Obama's in several countries that are considered US allies.

However, approval of US leadership actually increased in Russia and Israel.

The Gallup poll was based on asking questions of 1,000 random adults in 134 countries.
