Can LA function without undocumented labour?

As fresh protests erupt over President Trump’s immigration and deportation policies, we ask: how much does Los Angeles’s economy rely on undocumented workers? We speak to Julia Gelatt from the Migration Policy Institute and Mark Krikorian of the Centre for Immigration Studies.

Also on the programme: as the US–China trade dispute hits growth, both sides return to the negotiating table.

And we hear from Spanish meat producers concerned about the impact of potential US tariffs.
