He happily repeats the enduring myth that the UK is being swamped by a vast tsunami of foreigners who're plundering the country and leaving the rest of us destitute and done-for.
It's no good telling him that actually the immigration rate is still a minute percentage of the population (around 200,000 a year out of a population of 62 million) and hardly amounts to an uncontrollable deluge.
It's no good pointing out that many of these immigrants are highly skilled and greatly benefit the economy, and that they often take on vital jobs that other people don't want to do.
And it's no good suggesting that anyway the problem is not numbers but organisation, that if public services were better managed and new arrivals got more help to integrate into British life, there would be a lot less of the current hysteria and panic on the subject.
If it's really a question of numbers, how come people aren't bothered by the 790,000 new children who pour into the country every year? They also need things like schools, healthcare and housing. They also need to learn the language and learn how to integrate into British life.
But we're willing enough to organise that. We don't see children as a huge burden and liability we can't cope with. We don't demand a crackdown on childbirth. We see children as a potential asset, not a looming disaster.
Politicians should stop fanning xenophobic anxieties to improve their election prospects and set a more responsible example.
And pigs might fly.
