United Kingdom Shadow Foreign Secretary Emily Thornberry slammed President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power Two Louisville police officers shot amid Breonna Taylor grand jury protests MORE and said he is unworthy of a state visit when he visits the U.K.

Thornberry's statements came on Friday after he announced his decision to withdraw U.S. support for the United Nations Arms Trade Treaty.

“Donald Trump's statement on the Arms Trade Treaty is the final confirmation that he is not the Leader of the Free World, he never has been, and he does not deserve the honour of a State Visit to Britain,” Thornberry said in a tweet on Friday afternoon, referring to the president’s scheduled three-day visit to the country in June.

“He is nothing but a disgrace to his office and a threat to our world order,” she continued.

Trump said he would “never” ratify the United Nations Arms Trade Treaty while speaking at a National Rifle Association (NRA) convention in Indianapolis earlier on Friday.

“Under my administration, we will never surrender American sovereignty to anyone,” Trump said at the time. “We will never allow foreign bureaucrats to trample on your Second Amendment freedoms.”

The president then held up a paperwork that instructed the Senate to halt the ratification process before the cheering audience members.

“I hope you’re happy,” Trump told the guns rights advocates. The NRA has long opposed the international arms-trade treaty, which was signed by former President Obama in 2013.
