Boris Johnson has praised Donald Trump’s tweeting and called him one of the “great global brands” in a supportive interview on American television.

The Foreign Secretary told Fox News – Mr Trump’s favourite cable network – that he was penetrating the “global consciousness” more than many previous presidents.

Mr Johnson said that while some were frustrated with Mr Trump’s “rambunctious” tweeting, it was an effective method of communication.

The supportive intervention comes at a time when Mr Trump has the approval of just one in three Americans and is dogged by party splits and an investigation into his campaign’s Russia links.

It follows a deliberate attempt by the UK Government to get close to Mr Trump early in his presidency in an attempt to influence his decision-making.
