Left-wing Jeremy Corbyn was re-elected leader of Britain's opposition Labour Party on Saturday, after being challenged by Owen Smith.
Corbyn has faced allegations that his pro-Palestinian politics and endorsement of radical anti-Semites has encouraged hate speech against Jews.
He been accused of doing too little to curb rampant anti-Semitism among party members and lawmakers, some of whom have been suspended for making racist and anti-Semitic statements in public or on social media.
