Tottenham Hotspur fans who use the word "Yid" should not face prosecution, David Cameron has said.
The Prime Minister entered the row after the Football Association last week issued a statement warning supporters they risk receiving a banning order or even criminal charges if they continue to air the word.
For years Tottenham, who have a strong Jewish following, have been on the receiving end of anti-Semitic abuse from opposition fans.
In an act of defiance, some fans started using the word ''Yid'' themselves, and chants of ''Yids'', ''Yid Army'' and ''Yiddos'' are regularly sung in the home stands at White Hart Lane.
Mr Cameron told The Jewish Chronicle: "There's a difference between Spurs fans self-describing themselves as Yids and someone calling someone a Yid as an insult.
"You have to be motivated by hate. Hate speech should be prosecuted - but only when it's motivated by hate."
To those asking - yes I'm OK with David Cameron taking an opposing position to me on The Y-Word. To be honest, it's a dream come true.— David Baddiel (@Baddiel) September 17, 2013
The north London club responded to the FA warning by announcing they would send a questionnaire to all season ticket holders asking if the practice should stop.
Fans reacted defiantly to the FA's statement on Saturday as they chanted ''Yid Army'' and ''We'll sing what we want'' throughout the 2-0 win over Norwich.
