One year on, what has France's yellow vest movement achieved?

In many ways it is hard to believe that France's gilets jaunes, or yellow vest, movement is only a year old. In that time, it has led to a 10 billion euro ($11.05 billion) aid package for the poorest, changed laws and police tactics, cost the French economy billions of euros and forced a French president whose electoral platform was never to back down in the face of protest, to do just that.
