As far as I could see before I went to bed, most of the Brexit party gains were from UKIP. If they had no rebranded themselves it would have been a very good gain for UKIP but far from the landslide that the press are reporting.

Far more significant are the gains made by the pro-remain factions of LibDem, Green and the SNP. Both main parties suffered because of their stance, or non stance, on Brexit.

Europe wide the picture seems similar. Everyone is cheesed off with main stream politics. The populist right wing and the Greens have both done well because of this.

It seems that when a power vacuum is left by the mainstream, sensible people vote to save the planet while the easily led vote for those who tell them what they want to hear!
