England and France are at odds over how to deal with illegal migrants crossing the Channel, after 27 people died trying to get across.
It's the largest loss of life there in a decade.
Europe correspondent Vincent McAviney told Kate Hawkesby 25,000 migrants are trafficked across each year from Iran, Iraq, Syria and Eritrea.
He said they're smuggled by gangs from the Netherlands, Belgium and France.
McAviney said the French believe the coastline's too hard to police, so Britain's offering to send officers to help, but France is resisting that.
