'The Greatest National Anthem in the World, Ever'

In an act of solidarity in the wake of the Paris attacks, France's national anthem will be sung by English as well as French fans when the two nations' football teams meet at Wembley.

Historian Simon Schama explains how the power and emotion of La Marseillaise makes it the greatest national anthem in the world, while artist and animator Andrew Park reimagines Delacroix’s iconic painting Liberty Leading The People.
