Can Someone explain to me, Zemmmour doing very strongly in Paris XVI, Nevily Sur Seine etc (upwards of 16%!!!!)? The closest resemblance to these electorates seems like Wentworth or North Sydney. These electorates, no matter how anti-labor they are, would never vote for a far-right candidate. Similarly Kensington and Chelsea had very low UKIP vote shares.
Demographically UKIP was closer to Le Pen's base than Zemmour's, being stronger in working class suburbs and rural areas, so no surprise they didn't get traction in somewhere like K&C.
The closest UK equivalent of Zemmour would be someone on the more socially conservative wing of the Tories. I.e. Zemmour seems to have largely pulled off voters from the right of the corpse of LR.
