The rapper declined to comment on his use of the word 'Zionists' in the rap.
Footage of the performance has been shared on YouTube with the lyrics being praised by pro-Jeremy Corbyn website The Skwawkbox.
Lowkey, whose real name is Kareem Dennis, has previously made his anti-Zionist stance public on tracks such as Long Live Palestine, in which he sings: "You say you know about the Zionist lobby. But you put money in their pocket when you're buying their coffee. Talking about revolution, sitting in Starbucks."
In 2009 Lowkey, whose mother is Iraqi and father English. was questioned at Tel Aviv airport as he entered Israel.
He said at the time he had received a "minuscule fraction of the degradation Palestinian people are subjected to on a daily basis”.
The Charlie Sloth show has proved so popular that BBC has recently handed the presenter a further weekday evening slot.

This article and the headline have been amended to remove the incorrect suggestion that Lowkey referred to the “kosher nostra” during his rap
