In a statement, signed by a total of 117 MPs and 28 members of the House of Lords, the rhetoric used was described as being "dangerous".

The open-letter was coordinated by Labour MP Naz Shah, who told ITV News: "We can't remain silent and we must stand against racism and fascism. It's important we show people around the world, that British politicians won't tolerate this."
The chanting stemmed from Mr Trump tweeting that politicians, who he did not name, should “go back” to their countries.
He denied his tweets were racists and although Mr Trump did not initially say who he was referring to at his most recent rally he accused Ms Omar, Alexandria Ocasio-Cortez, Rashia Tlaib and Ayanna Pressley of hating America.
In response to the chants, Ms Omar tweeted a quote from Maya Angelou, the American poet, singer and civil rights activist: "You may shoot me with your words, you may cut me with your eyes, you may kill me with your hatefulness, but still, like air, I'll rise."
