A big congratulations to Linda Nelson who has just become a British citizen. Fraser details the long and taxing journey it took for his wife to reach this point in his Telegraph column this week and asks why as an immigrant nation do we make becoming British so challenging for new arrivals? 

On the podcast, Fraser talks with Cindy Yu and James Forsyth about this question. And Cindy brings a few questions from the citizenship test, to see if her colleagues would pass.
