How might Donald Trump or Kamala Harris try to tackle immigration to the US? People crossing the southern border has become a hot button topic in the next month’s election. Former president Donald Trump’s forceful policies have helped him motivate a base of loyal supporters. Whereas Vice-President Harris has had just weeks to convince Americans that she has a plan. What do we know about their policies, how they differ and what impact they would have?

Sumi Somaskanda speaks to our Mexico, Central America and Cuba correspondent, Will Grant. He explains why so many people are leaving the region and how the next president might impact its southern neighbours. And our politics reporter in Washington DC, Bernd Debusmann, helps us separate the facts from the headlines on one of the election's most contentious political issues.
