The anti-Front National coalition appears in crisis in France as infighting between establishment and populist factions continues to escalate.

Following the First Round victory for Emmanuel Macron, experts believed the independent candidate would easily triumph over Marine Le Pen in the Second Round, given the strength of mainstream backing.

But, critics argue the former investment banker has showed too much arrogance in the days following the win and risks blowing his lead.

Establishment figures such as Nicolas Sarkozy, Francois Fillon, Benoit Hamon and the current president Francois Hollande have backed Mr Macron.

However, Jean-Luc Melenchon, who came fourth last week, has refused to back either candidate.
