A rising star in the UK's Labour Party once compared Israel to the Nazis, it has been revealed.

Activist Jawad Khan shot to fame when he starred in a Labour Party Political Broadcast during the recent local and London Mayoral Elections in May. Khan himself stood in the local elections.

But the conservative Guido Fawkes political blog revealed Monday that less than two years prior, Khan had compared the State of Israel to the Nazis on Twitter.

In a tweet posted in August 2014, during Operation Protective Edge, Khan asked: "Anyone else see the similarities between Israel and the Nazis?"

That summer saw an unprecedented spike in anti-Semitism in Europe in particular, as well as in other countries around the world, as anti-Israel protests over Israel's operation to end attacks by Gazan terrorists regularly spilled over into anti-Semitic incidents. 

In the UK, many of the wave of suspensions of Labour Party activists and politicians earlier this year were enacted due to revelations of anti-Semitic posts made at the height of the conflict.

The latest revelation comes at an awkward time for Labour leader Jeremy Corbyn, who is currently facing widespread calls to resign for his handling of the party's campaign to remain in the European Union during the recent UK referendum. It comes less than a week after Corbyn himself came under fire for comparing Israel to ISIS.

Responding to the revelations, Khan told Guido Fawkes he had removed the tweet in question, and disavowed his previous position.

"I was 16 years old at the time and it was before I was involved in politics," he said. "The comment I tweeted was completely unacceptable and I later deleted it. I apologise unreservedly for making such an offensive comment."
