As of now the Brexit party holds 14MEP seats. Sunday that figure will change significantly if the polls are to be believed.
Along with Le Pens's party and others there will be a useful block of seats to stall the march of further integration within the EU.
No amount of chittering will alter this inescapable reality, neither will ridiculous labels such as the brexit clan dreamed up by those that endlessly demonstrate that they are totally incapable of reasoned responses.

A sea change is coming- anyone for a ride on the skylark? The blue is a rather fetching colour!
