'The key legacy of May 68 is the element of surprise'
1968 saw a wave of protests against the established order with calls for greater freedoms.

What followed were national protests, strikes and riots that left an indelible mark on today’s society. Today, French rail workers and students are angry at the government's reforms. We try to put what happened 50 years ago into a modern context with our guest, Professor François Cusset.
