They never receive any credit for it but the grooming gangs in the UK were first exposed decades ago by the now defunct British National Party.

And if you know anything about the British National Party they are a right wing nationalist party that DOESN'T suck up to israel or jews and are about as far from being Zionist as you can probably get. They are called a "fascist far right party" by wikipedia .
In fact that's the reason why the Zionists started propping up Tommy Robinson in the first place, to draw support away from the BNP and funnel anti-Islam sentiment in a direction that was more in their interests.
The current controlled opposition "right wing party" in the UK, the Reform Party was also created to destroy the British National Party to prevent British from going too far right wing.
Here is the Reform Party Leader basically admitting this. https://files.catbox.moe/kz637k.mp4
The BNP party IMPLODED on themselves with even a bit of power, it was a worse Tea Party movement.
Unfortunately unlike the Tea Party, they didn't set the stage for something like MAGA to happen, only UKIP and the one good thing of getting the UK out of the EU which combined with Migrants surging in seems to have stalled the EU growing in general.
So were they one of the first to raise it, yes. Did they do anything near as effective as Tommy Robinson in bringing attention or ANY pressure against it, no, they quickly became a joke with only 2 MEPs. Let's not rewrite history here as they were basically like Kanye West when he was interviewed by Alex Jones.
How'd BNP die?
From what I heard and remember, irrelevancy.
After gaining 2 MEP seats they squandered the platform they got to more enjoy the kickbacks. With this the EDL took their spot as a ground level rebellion party and UKIP focused that anger at getting out of the EU which was the establishments focus more than hiding the rape gangs. Over time they just faded out as they were no longer relevant.
