What is a 'pro brexit lie'?
Immigration will be reduced We will be able to negotiate excellent trade deals outside the EU effortlessly The EU need our trade so badly we will be able to negotiate a seamless trade deal with them … and many others.
Another faction of the pro-Brexiteers would think of the system in terms of a uniparty. The fundamentalists like Farage have no chance of getting elected as PM in the British system, though he did get an MP seat now.
Would things change if Farage were PM? I'm cynical, probably not.
