National flags reveal which borough has the highest number of people from each country, from Lambeth’s ‘Little Portugal’ to the Irish community in Brent and no fewer than nine nationalities in Westminster. A ‘no-deal’ Brexit would affect the whole city. But for those Londoners born in EU countries, the cliff edge is particularly worrying.
