He added: “Far worse hasn’t stopped me speaking my mind and defending our minorities.”
During his LBC show on Sunday, Mr Nawaz had described Labour as “institutionally antisemitic” in response to new allegations over the party’s disciplinary processes.
Later, he told listeners: "While live on air whilst speaking I received a very graphic death threat. Because that's the climate of fear that this kind of racism has led to.
"I posted it because I want people to understand how scared the Jewish communities must feel, who regularly deal with anti-Semitic hate crime incidents year in, year out.
"I'm not going to let such intimidation scare me, I've been through must worse than that.
"But this petty and cowardly threat to my life will not deter me to speaking up in favour of our minority communities across the board."
