Is the UKIP still a relevant party in any way?
Trouble is, the UK political scene is currently entirely populated by people who lack the competence to realise there is anything wrong with their own strategies. (All of them, including the groups I used to consider ‘my side’).
So, they might be relevant by default.
They are still going under different leadership, focusing on other typical right-wing issues. Depending on how things go with Brexit they might well come back into the limelight this year.
