Ah, so the plan is to count up the votes of the various, different, Left-wing Parties - all of which have Rejoin in their manifesto - and come to an overall total of +50%, meaning they can do so without a specific referendum!
Well, that's your intel comrades. Act accordingly...🧐
Labour winning the next General Election could well be considered a mandate to hold a new National Referendum on joining the EU.
But winning power with less than 50% of the total vote would not, in itself, be a mandate to rejoin the EU without another Referendum!
Everyone clear?
