Nigel Farage’s new party tops the polls with 27% of the vote

In our first poll on the forthcoming EU Parliament elections last week Nigel Farage’s new outfit stormed into third place with 15% of the vote. This was despite the Brexit Party not having formally launched.

Now, following the burst of publicity that came with their official formation, our second poll, conducted for the People’s Vote, shows the Brexit Party leapfrogging into first place on 27% of the vote.
