We've all been involved in the argument at one point or another. Are you from the north or the south?
Many of us living in London have travelled south to the city in search of work, lifestyle, fame and fortune and anything else the capital has to offer.
And this means many may have been accused of being a 'northerner', perhaps rightly or wrongly.
Is it right to think yourself northern because you come from near Leicester? Or does a hometown anywhere north of Watford mean you no longer qualify as a southerner?
