Fox News contributor Nigel Farage said President Trump's "bombshell" comments about British Prime Minister Theresa May's handling of Brexit stunned the political establishment in the United Kingdom.

In an interview with The Sun, Trump said May had ignored his advice on Britain’s departure from the European Union.

He said that May’s new, softer approach to Brexit -- which would leave Britain sticking to a “common rulebook” with Brussels on goods -- would kill off the chances of a much sought-after U.S.-U.K. trade deal.

Farage, a member of European Parliament and former leader of the U.K. Independence Party, said Trump decided to "intervene" for two reasons: he believes in Brexit and he feels the U.S. has been let down.

"He believes in a world of democratic nation-states cooperating with each other, not globalist structures like the European Union," Farage said.

He argued that May, who voted "Remain" in the 2016 referendum on leaving the EU, is not up to the job of giving U.K. citizens the Brexit they voted for.

"The sense of betrayal in this country will be huge, and I very much hope that she's out of office before too long," Farage said.
