Donald Trump Jr. claimed that British democracy is "all but dead" as he lashed out against Downing Street, writing in his recent article, retweeted by the vocal Brexiteer and former UKIP leader, Nigel Farage.
Trump Jr. likened UK's withdrawal from the European Union to his father's election.
"In a way, you could say that Brexit and my father's election are one and the same. The people of both the UK and the US voted to uproot the establishment for the sake of individual freedom and independence, only to see the establishment try to silence their voices and overturn their mandates. What we're seeing now in Washington, London and Brussels is the desperate, last-gasp attempt by those previously in power to cling on to what was once theirs in the face of an overwhelming mandate for change," he said.
He has also lashed out against the UK PM for "sabotaging" Brexit and failing to "honour" her promise to the British people that they will see Brexit take place on 29 March 2019.
"But Mrs. May ignored advice from my father, and ultimately, a process that should have taken only a few short months has become a years-long stalemate, leaving the British people in limbo," Donald Trump Jr. argued.
