"My big fear was, at some point, maybe very soon, he'd be out free on the streets."
Mr Farage's reaction comes just two hours after jurors found 26-year-old Afghan Fayaz Khan guilty of making a threat to kill the leader of Reform UK.
Khan, who is also known by his TikTok name Mada Pasa, appeared to tell his 340,000 followers: "Englishman Nigel... don't talk s**t about me.
"I come to England because I want to marry your sister. I want to come to England to go pop pop pop."
The 26-year-old, who has AK-47 tattoo on his face, made 10 attempts to reach Britain via small boat before finally crossing the Channel on October 31 last year.
