Nations need borders
Sir: Austen Ivereigh (‘Let’s sort out the migration mess’, 17 March) argues that giving an amnesty to the 500,000-odd illegal immigrants in Britain offers a practical solution to our immigration problem. The policy sounds wonderful and comforting, but the reality is that it will send out a trumpet call to people to come here illegally in the knowledge that they will be made legal later. The experience of the United States makes the point. Since 1986 alone, it has given seven amnesties covering millions of illegal immigrants. The result has been that the number of illegal immigrants has rocketed from below four million in 1980 to around 10 million today (accounting for 30 per cent of the foreign-born population).
