How can more Channel tragedies be stopped?

Available for over a year

A pregnant woman and six children are among the dead after a small boat capsized in the Channel in the worst tragedy of its kind this year. We're live on the French coast - and ask whether the new government's plan to "smash the gangs" will help to prevent future tragedies. Also tonight: The final report into the Grenfell Tower fire is published tomorrow - we hear what it means to survivors. And as a street in Prague is named after Sir Nicolas Winton - we speak to one of the children he rescued from the Nazis and who was there for the ceremony.
